Ok hey guys 11 its and explain so convert this into vertex form y=-2x^2 + 16x-37

Vertex form is y=a (x-h) ^2+k

basically complete the square

isolate the x^2 and x term, then undistribute the - 2

y=-2 (x^2-8x) - 37

take 1/2 of - 8 and square it and add 0 to inside

y=-2 (x^2-8+16-16) - 37

complete the squaer

y=-2 ((x-4) ^2-16) - 37)

distribute the - 16 to the - 2

y=-2 (x-4) ^2+32-37

y=-2 (x-4) ^2-5
