# Chapter 9 - Quadratic Functions and Equations - 9-3 Solving Quadratic Equations - Practice and Problem-Solving Exercises - Page 552: 55

a) $=6*(B2)^2-24$ b) $x=2, x=-2$ The table showed what integers made the equation equal zero. c) A spreadsheet can provide the answers for non-integer answers.

#### Work Step by Step

$6x^2-24= 0$ $6x^2-24+24= 0+24$ $6x^2 = 24$ $6x^2/6 = 24/6$ $x^2 = 4$ $\sqrt {x^2} = \sqrt 4$ $x=2, x=-2$
