The values ofxare-6and2

Step by step solution

01

Step 1. Given information and definition

According to square root property, if we have an equation with a perfect square on one side and any number on the other side, then we can take the square root of both sides and add a plus or minus sign to the side with the number.

Given the quadratic equation x+22=16

02

Step 2. Use square root property 

鈬�x+2=卤16

鈬�x+2=卤4

鈬�x=-2卤4

鈬�x=-6andx=2
