Question 1121316: Hello! I'm not sure how to write this equation into standard form. This is the vertex form of the equation and I need to convert it to standard form.
y = 4(x + 5) - 2(x + 1)^2

Any help would be appreciated, thank you!

expand everything
y=4x+20-2(x^2+2x+1)
=4x+20-2x^2-4x-2
=-2x^2+18 This is one form of standard
another form (vertex to me, but some call standard) would be y=-2(x-0)^2+18
