Chapter 4 Quadratic Functions and Factoring - 4.8 Use the Quadratic Formula and the Discriminant - Guided Practice for Examples 1, 2, and 3 - Page 293: 1

Answer

$$x=5.24,.764$$

Work Step by Step

We first check that the function is in the form $ax^2+bx+c$. Then, using the quadratic formula, we obtain: $$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$$ $$x=\frac{6\pm \sqrt{(-6)^2-4(4)(1)}}{2(1)}$$ $$x=5.24,.764$$
