Question

What is
f(x)= (x-12)(x+1)
in standard form?

Answer 1

x^2-11x-12

Explanation:

I use the box method, which makes a 2x2 box. Then you arrange you numbers based on the equation (show in image)

Then you multiply it out and get the equation

F(x)= x^2+x-12x-12

Simplify your equation and you get

F(x)= x^2-11x-12
