## ashleysmith Group Title solve by completing the square. x(to 2nd power) -6x-16=0 2 years ago 2 years ago

1. SmoothMath

The first thing to do is make it look like something you can complete the square for. Get the x^2 and the x part of the equation alone.

2. cwtan

Completing the square (x-3)^2-3^2-16=0

3. cwtan

(x-3)^2=25 x-3=$$\pm$$5
