Question

Write a quadratic function in standard form having zeros of -9 and -12.

Answer 1

y = 0 @ x = -9 and x = -12
so that gives the factors of
(x+9) and (x+12)

[as (-9 + 9) = 0
and (-12 + 12) = 0

so multiply out (x+9)(x+12) ricardo, that'll be ur quadratic

Answer 2

standard form should resemble :
\[y = ax^2 + bx + c\]

Answer 3

u all good with that dude...?

Answer 4

yeah! thanks!

Answer 5

sweet as bru

Answer 6

So would the work look like this?

\[x = -9, x = -12\]
\[y = (x - 9)(x - 12)\]
\[y = x^2 - 21x + 108\]
