Express x^2+5x-2 in the form of a(x+h)^2+k. Hence solve x^2+5x-2=0
We'll use "completing the square" method here...
x^2+5x-2 = 0 take 1/2 of the 'x' number 2.5 square it ...and add it to both sides
x^2 + 5x + 6.25 -2 = 6.25
(x+2.5)^2 - 8.25 = 0
(1) (x+2.5)^2 - 8.25 = 0 There ya go ! a= 1 k = -8.25 h= 2.5
