WebMar 30, 2015 · If x2 + 8x are the first 2 terms of a squared expression. the third term must be (8 2)2 = 16. Add 16 to each side of the equation, giving. x2 +8x + 16 = 23. which is the … WebAlgebra. Solve by Completing the Square x^2+8x+15=0. x2 + 8x + 15 = 0 x 2 + 8 x + 15 = 0. Subtract 15 15 from both sides of the equation. x2 + 8x = −15 x 2 + 8 x = - 15. To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b b. (b 2)2 = (4)2 ( b 2) 2 = ( 4) 2.
