Question: 1 / 410

Which is the solution of the equation 2x2 + 5x – 3 = 0?

–2 and 3/2

–2 and 0.6

To solve this equation, we can use the quadratic formula (-b ± √(b^2 - 4ac)) / 2a, where a, b, and c are the coefficients of the equation. In this case, a = 2, b = 5, and c = -3. Plugging these values into the formula, we get (-5 ± √(5^2 - 4(2)(-3))) / 2(2), which simplifies to (-5 ± √(25 + 24)) / 4. This gives us two possible solutions x = (-5 + √49) / 4 = -2 and x = (-5 - √49) / 4 = 0.6. Therefore, the correct answer is B, as it includes both of these solutions.
