Chapter 4 Quadratic Functions and Factoring - 4.3 Solve x(squared) + bx + c = 0 - 4.3 Exercises - Skill Practice - Page 256: 35


0, -9

Work Step by Step

Since the coefficient of the squared term is one, we know that the expression must factor to: $$ (u\pm a)(u\pm b)$$ Here, we see that a and b must multiply to get $0$ and add to get $9$. Thus, we find that the solution is: $$(u+0)(u+9)$$ Thus, setting each factor equal to zero, we find that the solutions are: $$0,-9$$
