Send it here

#

can we start with just one or two

fossil bridge
fossil bridge
leaden zenith
#

ok

#

first try yourself here,

fossil bridge
#

@prisma siren ? were you also typing?

fossil bridge
leaden zenith
#

ok

prisma siren
leaden zenith
#

as it says, there are 3 methods of solving a quadratic :
(i) factorisation
(ii)completing the square

#

and quadratic formula

#

1st exercise is about factorisation

prisma siren
#

Where (ii) is basically equivalent to (iii) (completing the square is how you prove the quadratic formula)

#

Why are quadratic equations class 11, for us it's calculus

leaden zenith
#

fior us it's class 9

fossil bridge
#

I need help nothing more

leaden zenith
#

ok

#
  1. 3x^2 +4x +1
fossil bridge
leaden zenith
#

now we will split the middle term

fossil bridge
leaden zenith
#

yes

fossil bridge
#

then i think take commom?

leaden zenith
#

but you know why we need only 3x and x, and not somwthing else?

#

ignore my spelling

leaden zenith
fossil bridge
leaden zenith
#

yes

fossil bridge
leaden zenith
#

now it is 3x^2 +3x + x +1

fossil bridge
#

i got 2 values (3x+1)(x+1)

#

now i think we have to make them equal to 0

leaden zenith
#

yes

fossil bridge
#

seperatly?

#

3x+1=0

leaden zenith
#

yup

fossil bridge
#

x= -1/3

#

&

#

x=-1

leaden zenith
#

yes

fossil bridge
#

then what i have to do

leaden zenith
#

next move on

fossil bridge
#

wait let me take my Helping book

rapid garden
leaden zenith
fossil bridge
#

so we will discuss on that question where i ahve issue

fossil bridge
leaden zenith
#

next........

fossil bridge
leaden zenith
#

ok

#

take your time

fossil bridge
#

lets take q5

#

from exercise

#

how to solve it?

leaden zenith
#

ok

#

first open brackets on both sides

fossil bridge
#

opened

leaden zenith
#

what do you get?

fossil bridge
leaden zenith
#

now transfer all terms on LHS

#

some will cancel out

fossil bridge
#

yeah

#

solved it

#

it becomes a simple formula

leaden zenith
#

yes

fossil bridge
#

a^2-b^

leaden zenith
#

yup

fossil bridge
#

so from there I'll get values

leaden zenith
#

x=?

fossil bridge
#

x=2 , x=-2

leaden zenith
#

👍

fossil bridge
#

Now q6

#

it has values in over

#

Difficult for me

leaden zenith
#

first make the denominator common

#

make everything into a single fraction

fossil bridge
#

yeah am taking lcm

#

then I'll do cross multiply

#

I solved it

leaden zenith
#

answer?

fossil bridge
#

I stuck on q8

#

How to solve it

leaden zenith
#

what do you get in the numerator?

fossil bridge
#

How we can easily solve this

#

should i take LCM?

leaden zenith
#

yes

fossil bridge
leaden zenith
#

you'll need that to do something further

leaden zenith
fossil bridge
fossil bridge
#

I got

#

abx-a+abx-b/abx^2-ax-bx+1

#

what i do further

#

waiting

#

@leaden zenith

leaden zenith
#

it becomes 2abx-a-b

#

the textbook does it some other way

#

this one we're doing seems time consuming

fossil bridge
#

They used a trick

leaden zenith
#

lemme check

fossil bridge
#

That i didn't . this thing make me much boring. That i stuck on problem & don't knwo what to do next

#

yeah

#

so what i to do?

#

how we have to solve it easily

#

leave it

#

Lets try to solve question

#

what i have to do?

deep wolf
#

I suggest you leave this weirdo

fossil bridge
#

you have to tell how to solve it

#

what should i do first?

#

LOL

#

this was 1st hard question

#

Then?

#

Well

#

So, should we continue?

#

what do you mean?

#

solve on a paper and send a snip?

#

Bruh, na

#

just we have to solve 20 questions today

#

just 20 questions now we're on 8

#

8

#

I was seeing on Helping book+ on YT

#

Nope

#

Wrong there was a condition on Question

#

Btw, I solved it

#

Lets move on further

#

Dude, Your answer is wrong. Try to focus on it

#

Yeah wait let me check

#

that i can do it or not

#

Yeah guide me about Completing square

#

How to solve 9

#

is it 9?

#

wrong answers

#

here answer is -29,31

#

but 2nd?

#

yes

#

Sorry

#

LOL

#

Sorry

#

but you haven't told how to solve step by step

#

Sad

#

My math is too poor

#

Yeah, as you're tolding in above message. YOu sent a solved question

#

I have multiple Helping books in front of me

#

I sloved upto q14

#

I done my completing square questons by just seeing helping book once

#

nah now q15 onwards quadratic formula

#

LOL

#

wtf
