Find the solution(s) to 22 +57-3 = 0. Check all that apply.

irakobra [83]

Answer:

x = -3 and x = 1/2

Step-by-step explanation:

To find the solutions to

2x² + 5x - 3 = 0

we can use the quadratic formula, as follows:

$x = \frac{-b \pm \sqrt{b^2- 4(a)(c)}}{2(a)}$

$x = \frac{-5 \pm \sqrt{5^2- 4(2)(-3)}}{2(2)}$

$x = \frac{-5 \pm 7}{4}$

$x_1 = \frac{-5 + 7}{4}$

$x_1 = 0.5$

$x_2 = \frac{-5 - 7}{4}$

$x_2 = -3$
