How do i complete the square x squared plus 10x minus 13 equals 17 how do you complete the square x squared plus 10x minus 13 equals 17?
X2 + 10X - 13 = 17
add 13 to each side
X2 + 10X = 30
halve the linear coefficient ( 10 ), square it and add it to both sides
X2 + 10X + 25 = 30 + 25
factor on the left and gather terms on the right
(X + 5)2 = 55
(X + 5)2 - 55 = 0
---------------------------vertex form, (- 5, - 55 ), is the vertex
