Answer:
To complete the square move the non-x term to the right
2x^2 + 13x = -20 then divide equation by x^2 coefficient
x^2 + 6.5x = -10
then coefficient of x (which is 6.5) divide by 2 (3.25) square the number
=10.5625 Then add 10.5625 to both sides of the equation:
x^2 + 6.5x + 10.5625 = -10 + 10.5625
x^2 + 6.5x + 10.5625 = .5625
Take the square root of both sides
(x + 3.25)^2 = .75
