Question

Write a quadratic function in standard form having zeros of -5 and 1.

Answer 1

Use this f(x)=(x-a)(x-b) where a and b are your zeros.

Answer 2

I don't get what that equation is though.. @math&ing001

Answer 3

Example suppose your zeros are 9 and -7
f(x) = (x-9)(x-(-7)) = (x-9)(x+7) = x^2+7x-9x-63 = x^2 - 2x - 63
so
f(x)= x^2 - 2x - 63 is the quadratic function in standard form

Answer 4

oh ok!!

Answer 5

would this one be
x^2+4-5?

Answer 6

@math&ing001

Answer 7

Yep ! Don't forget the x near 4.

Answer 8

oh thank you!!! <3
