Question

Find the roots of quadratic equation -2x^2+3x+2=0 by factorization method .​

Answer 1

Answer:

x= 1/2 , -2

Step-by-step explanation:

$- 2x {}^{2} + 3x + 2 = 0 \\ - 2x {}^{2} + 4x - 1x + 2 = 0 \\ - 2x(x + 2) - 1(x + 2) = 0 \\ (- 2x - 1) (x + 2) = 0 \\ - 2x - 1 = 0 \: \: \: \: or \: \: \: \: x + 2 = 0 \\ - 2x = 1 \: \: \: \: or \: \: \: \: x = - 2 \\ - x = \frac{1}{ 2} \: \: \: \: or \: \: \: \: x = - 2$
