Question

Find the solution set 7x^2-9x-10=0

Answer 1

x = -5/7 or x = 2

Explanation:

7x² - 9x - 10 = 0

Factor the left side of the equation.

(7x + 5) (x - 2) = 0

Set the factors equal to 0.

7x + 5 =0

7x = -5

x = -5/7

x - 2 = 0

x = 2

Answer 2

x = -5/7, 2

Explanation:

Step 1: Factor

(5x + 7)(x - 2) = 0

Step 2: Find x roots

5x + 7 = 0

x = -5/7

x - 2 = 0

x = 2
