Write the equation in standard form. then factor the left side of the equation. 2x^2 + 7x = 15

2x^2 + 7x - 15 = 0

Factors: (2x - 3)(x + 5)

Step-by-step explanation:

To write the equation in standard form rearrange to this form ax^2 + bx + c = 0. Rearrange the equation 2x^2 + 7x = 15 by subtracting 15 from both sides.

2x^2 + 7x - 15 = 0

The left side factors into (2x - 3)(x + 5) since it multiplies to 2x^2 - 3x + 10x - 15 = 2x^2 + 7x - 15.
