idkkk its a worksheet :/

Answer 5

for example if i have x^2+2x+1
so we will have something like this
(x+?)(x+?) right?

Answer 6

I guess :/

Answer 7

to find what goes in those question marks, you have to write the equation in standard form, lucky u it already is in it
ax^2+bx+c

Answer 8

so now in the case of x^2+2x+1
1 = a, because x^2 = 1x^2
2=b
and c = 1

Now we need to find 2 numbers that add together to b and multiply together to the product of a and c

Answer 9

so what 2 numbers multiply to the product of a and c (which is 1 times 1) and add together to b (which is 2)
