Question: 1 / 410

What is the solution for x in the equation 2x2 + 3x - 6 = 0?

x = -2

To solve this equation, we need to use the quadratic formula, which is

x = (-b ± √(b2-4ac)) / 2a.

In this equation, a = 2, b = 3, and c = -6.

Plugging those values in, we get x = (-3 ± √(9+48)) / 4.

Simplifying, we get x = (-3 ± √57) / 4.

From here, we can see that the solutions are x = -(3/4) ± √(57)/4.

Since the square root of 57 is not a perfect square, the solutions will be irrational.

However, when we simplify further, we can see that the only rational solution is when x = -2.
