firstly

Damn

don't lose the brackets
your 3rd line is gonna lose you accuracy marks
leave it as (x^2 + 7x + 10)(x+a)
then expand it as usual
x^3 + 7x^2 + 10x + ax^2 + 7ax + 10a
x^3 + (7+a)x^2 + (10+7a)x + 10a

# quartz wagon Brooo

u clearly didn’t explain it to me well earlier bc it doesn’t work here

#

so how do I find a and c

#

🙂

quartz wagon
#

It does tho you just compare the coefficients once again

dense ridge
#

IT DOESNT WORK

stark patio
#

it does work

dense ridge
#

HOE

quartz wagon
#

💀

dense ridge
#

How*

stark patio
#

compare each x term

#

all the x^3 terms must be equal on the left and right , same with x^2 terms, x terms and then constants

dense ridge
#

So is it Square route of 7

#

what is this topic called aswell

stark patio
#

ok so expand the right hand side properly and set equal to the left hand side
x^3 + (7+a)x^2 + (10+7a)x + 10a = x^3 + bx^2 + cx - 30
Looking at the terms with no x (constants)
10a = -30
a = -3
looking at x^2 terms
7+a = b
4=b
looking at x terms
10+7a = c
-11 = c

hm okay….

haughty void
dense ridge
#

im still a bit lost but tyy

haughty void
#

all you do is compare the coefficients of the x terms

#

and solve for the unknown variables

dense ridge
haughty void
#

probably

#

look it up

#

mk thanks
