Step 1
2x23=125
Subtract 125 on both sides
2x2128=0
Divide both sides by 2
x264=0
Using
a2b2=(a+b)(ab)
x264=(x+8)(x8)
So
(x+8)(x8)=0
x=±8

Step 1 Move all the terms to one side of the equation 2x23=125 2x23125=125125 2x2128=0 Now take out a factor of 2 (2×x2)(2×64)=0 2(x264)=0 We now have a term in the parentheses that looks like (a2b2) This is called a difference of squares We can factor a difference of squares like this: (a2b2)=(ab)(a+b) Lets
