To solve the quadratic equation \(x^2 + 3x - 10 = 0\) by factoring, we first need to factor the quadratic expression.
We want to find two numbers that multiply to \(-10\) (the constant term) and add to \(3\) (the coefficient of the \(x\) term). The numbers that meet these criteria are \(5\) and \(-2\) because:
- \(5 \times (-2) = -10\)
- \(5 + (-2) = 3\)
Thus, we can factor the quadratic as follows:
\[
(x + 5)(x - 2) = 0
\]
Now, we can use the zero-product property. Set each factor equal to zero:
1. \(x + 5 = 0\) → \(x = -5\)
2. \(x - 2 = 0\) → \(x = 2\)
Therefore, the solutions to the equation \(x^2 + 3x - 10 = 0\) are:
- \(x = -5\)
- \(x = 2\)
