Math Problem Statement

factor

Factor the quadratic equation x^2 + x - 30.

Solution

The text extraction from the image did not succeed, but I can clearly read the equation x2+x30x^2 + x - 30 from the image you provided. Let's factor this quadratic equation.

We are factoring x2+x30x^2 + x - 30.

To do this, we look for two numbers that multiply to give 30-30 (the constant term) and add to give 11 (the coefficient of xx).

The numbers are 66 and 5-5, because:

6×5=30and6+(5)=1.6 \times -5 = -30 \quad \text{and} \quad 6 + (-5) = 1.

So, we can factor the equation as:

x2+x30=(x+6)(x5).x^2 + x - 30 = (x + 6)(x - 5).

Thus, the factored form is:

(x+6)(x5).(x + 6)(x - 5).
