Question

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

Answer 1

A and D are the answer.

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 = (1)/(2)`
