Question

Use the zero product property to find the solutions to the equation 2x2 + x – 1 = 2.

Answer 1

$2 {x}^{2} + x - 1 = 2$

Subtract sides -2

$2 {x}^{2} + x - 1 - 2 = 2 - 2$

$2 {x}^{2} + x - 3 = 0$

$(x - 1)(2x + 3) = 0$

_________________________________

$x - 1 = 0$

$x = 1$

##############################

$2x + 3 = 0$

$x = - \frac{3}{2}$
