Question

Rewrite the equation in standard form by expanding it.
y= 3 (x+2)^2 - 4

Answer 1

y = 3x^2 + 12x + 8

Explanation:

To rewrite in standard from by expanding the equation using the distributive property.

y= 3 (x+2)^2 - 4

y = 3(x^2 + 4x + 4) - 4

y = 3x^2 + 12x + 12 - 4

y = 3x^2 + 12x + 8
