Question

quadratic formula for y = x^2 + 10x + 16

Answer 1

do you know the quadratic formula ? ;)

Answer 2

no need to graph the result

Answer 3

are the answer choices as graphs ?

Answer 4

yes

Answer 5

okay well then yes ! but you have to use the quadratic formula for this

Answer 6

that is the formula now plug in the numbers from you equation to get the answer

Answer 7

1. x^2 -2x - 8x +16 = 0
2. x ( x-2) - 8 ( x- 2) = 0
3. ( x-8) ( x-2) = 0
4. x = 8 OR 2
or do it like this

Answer 8

this is what it should look like

Answer 9
