y=(x+4)^2+4 in standard form

1 answer

To put the equation y = (x + 4)^2 + 4 in standard form, we need to expand and simplify it.

y = (x + 4)^2 + 4
y = (x + 4)(x + 4) + 4
y = x^2 + 4x + 4x + 16 + 4
y = x^2 + 8x + 20

Therefore, the standard form of the equation y = (x + 4)^2 + 4 is y = x^2 + 8x + 20.
