the standard form of the equation of a parabola is x-y^2+10y+22.what is the vertex form of the equation?
A.x=(y+10)^2-78
B.x=(y+5)^2+12
C.x=(y+5)^2-3
D.x=(y+10)^2+2

Respuesta :

x = y^2 + 10y + 22

Divide 10 by 2  to give 5  which  becaoses the second term in the parentheses

x = (y + 5)^2 - 25 + 22

x = (y + 5)^2 - 3   Answer.
