Explanation:
The standard form of the quadratic equation is
y=ax2+bx+c
However, you have been given an equation in vertex form
y=5(x8)2+11
First, factor out the (x8)2 term using the FOIL process
y=-5(x-8)(x-8)+11
y=5(x28x8x+64)+11
y=5(x216x+64)+11
Next, multiply the -5 through the factored expression.
y=5x2+80x320+11
Finally, add the last two terms
y=5x2+80x309
