Question

Solve by factorization 2x squared +3x-20=0

Answer 1

Answer:

2x²+8x-5x-20

2x(X+4)-5(X+4)

2x-5=0, X+4=0

X=5/2 X= -4

Answer 2

$2 {x}^{2} + 3x - 20 = 0 \\ 2 {x}^{2} + 8x - 5x - 20 = 0 \\ 2x(x + 4) - 5(x + 4) = 0 \\ (2x - 5)(x + 4) = 0 \\ \\ 2x - 5 = 0 \\ x = \frac{5}{2} \\ and \\ x + 4 = 0 \\ x = - 4$
