Chapter 6 - Section 6.6 - Solving Quadratic Equations by Factoring - Exercise Set: 17


The solutions are -0.2 and -1.5.

Work Step by Step

(x+0.2)(x+1.5)=0 x+0.2=0 or x+1.5=0 x+0.2-0.2=0-0.2 or x+1.5-1.5=0-1.5 x=-0.2 or x=-1.5 The solutions are -0.2 and -1.5. Check Let x=-0.2 (-0.2+0.2)(-0.2+1.5)=0 0(1.3)=0 0=0 Let x=-1.5 (-1.5+0.2)(-1.5+1.5)=0 (-1.3)0=0 0=0
