Question

What is the sum of 2x² +3x -5

Answer 1

Answer:

$2 {x}^{2} + 5x - 2x - 5 = 0$

$x(2x + 5) - 1(2x + 5) = 0$

$(2x + 5)(x - 1) = 0$

$2x + 5 = 0 \: \: \: \: \: \: \: or \: \: \: x - 1 = 0$

$2x = - 5 \: \: \: \: \: \: \: or \: \: \: \: x = 1$

$x = \frac{ - 5}{2}$

ANS :

$x = \frac{ - 5}{2} \: or \: 1$
