#### Answer

The solutions are -1.7 and -2.3.

#### Work Step by Step

(x+1.7)(x+2.3)=0
x+1.7=0 or x+2.3=0
x+1.7-1.7=0-1.7 or x+2.3=0-2.3
x=-1.7 or x=-2.3
The solutions are -1.7 and -2.3.
Check
(x+1.7)(x+2.3)=0
Let x=-1.7
(-1.7+1.7)(-1.7+2.3)=0
0(0.6)=0
0=0
Let x=-2.3
(-2.3+1.7)(-2.3+2.3)=0
(-0.6)0=0
0=0
