From polynomials

un readable

[distant lake]

🥶 hold on let me get my ocr

[distant lake]

Zoom in

[mystic swallow]

wait

[distant lake]

The ocr failed 😔

[mystic swallow]

@distant lake send the top part of the graph

[distant lake]

The parabola cuts y axis at 30, 0 and x axis at (-7, 0) and (10, 0)

[mystic swallow]

haha

let's go though this togheter

ii)

first we can see that the roots are x = - 7 and 10

so product of roots is -70

sum is -3

is 3 = 1/70?

idts

[distant lake]

anyways the equation I formed is x² - 3x - 70

[mystic swallow]

nahh

[distant lake]

😭

Looks like i lost one mark

[mystic swallow]

first of all

it's -p(x)

[distant lake]

Hey did I at least do the second part right ?

I wrote -70

[mystic swallow]

@distant lake it's

$\frac{-30}{70}(x+7)(x-10)=y$

Oh

[mystic swallow]

the front part is so that when x = 0(it cuts y), it does so at 30

and the graph is upside down

so we add a -

[distant lake]

its ok everyone messed this question up in my class at least

[mystic swallow]

it's elementary

bad class

[distant lake]

Half the class skipped this thing

After all its, 10th F
