Question

Select the two values of x that are roots of this equation 2x^2+5x-3=0

Answer 1

Answer:

A and D are the answer.

Step-by-step explanation:

We can factor this by grouping

$2 {x}^{2} + 5x - 3$

$2 {x}^{2} + 6x - x - 3$

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

The roots are

$(x + 3) = 0$

and

$2x - 1 = 0$

Let solve for zero in each roots.

$x = - 3$

$2x = 1$

$x = \frac{1}{2}$
