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
