I'm assuming x2 means x^2, so the polynomial is unable to be factored so you plug it into the quadratic formula. (-b + / - sqr (4ac-a^2)) / 2a. Once you do this your final product is positive/negative 7/9

Kathryn · Answer 2

Since 2x and 5x have the same variable u have to add them

2x + 5x = 7x + 9

7x + 9 will be the answer
