Changing from vertex form to standard form (Algebra) please help?

vertex form is a(x - h)^2 + k





Standard from is y= ax^2 + bx + c











if my equations are


1.) f(x)= -2(x - 1)^2 + 10


2.) f(x)= 2x^2 - 8





(how do i put this in standard form?)

f(x)= -2(x - 1)^2 + 10





y = -2(x - 1)^2 + 10





y = -2(x^2 - 2 x + 1) + 10





y = -2 x^2 + 4x - 2 + 10





y = -2 x^2 + 4x + 8











f(x)= 2x^2 - 8





y = 2x^2 + 0x - 8
Reply:expand and group like terms.


I'll do the first one





-2(x-1)^2 + 10





=(-2x - 1)^2 + 10


=(-2x-1)(-2x-1) + 10


= 4x^2 +2x +2x +1 +10


= 4x^2 +4x + 11
