Solve the quadratic equation by factoring, show work. 2x^{2} +x-15=0

x = -3 or x = 5/2

Step-by-step explanation:

Solve for x:

2 x^2 + x - 15 = 0

The left hand side factors into a product with two terms:

(x + 3) (2 x - 5) = 0

Split into two equations:

x + 3 = 0 or 2 x - 5 = 0

Subtract 3 from both sides:

x = -3 or 2 x - 5 = 0

Add 5 to both sides:

x = -3 or 2 x = 5

Divide both sides by 2:

x = -3 or x = 5/2

15% chance.
