Write the quadratic function in standard form.


y=(x-8)^2 +9


I will report if you do not show you work, or your answer is incorrect.

Answer 1

Use the FOIL to solve

1) Expand

(x-8)(x-8)+9

x^2,-8x,-8x,64 +9

add like terms

x^2-16x+73

y=x^2−16x+73

Answer 2

here it is, step by step.

y = (x-8)(x-8) + 9
y = x^2 - 8x - 8x + 64 + 9
y = x^2 - 16x + 64 + 9
y = x^2 - 16x + 73

this is standard form! i hope it helps. ❤️
