Question

Solve the following Quadratic Equations?
 2x2 – 15x – 8 = 0

anonymous · Answer

2x^2 - 15x - 8 = 0.

(2x + 1)(x - 8) = 0.

2x + 1 = 0. 2x = - 1. x = - 1/2. One Answer.

x - 8 = 0. x = 8. Second Answer.

2x^2 – 15x – 8 = 0
2x^2 -16x + x - 8 = 0
2x(x-8) + (x-8) = 0
(2x+1) ( x-8) = 0
So, 2x+1 = 0    or    x-8 = 0   <- solve these two equations.
