If 3x^2 + 7x - 10 = 0, what is the value of x?

  1. 10

  2. 7

  3. -10

  4. 3

The correct answer is: 3

To solve this quadratic equation, we can use the quadratic formula or factor the equation. Option A, 10, is incorrect because it is the constant term in the equation but not a possible solution for x. Option B, 7, is incorrect because it is the coefficient of the x term but not a possible solution for x. Option C, -10, is incorrect because it is the constant term in the equation but again, not a possible solution for x. Option D, 3, is the correct answer because it is the only solution that satisfies the equation when substituted. Additionally, Option D can also be found by factoring the equation into (3x-2)(x+5) and solving for x. Therefore, the value of x is 3.
