(13-2x)(13-2x)
(13+-2x)(13+-2x)
(13)(13)+(13)(-2x)+(-2x)(13)+(-2x)(-2x)
169-26x-26x+4x^2
4x^2-52x+169
I hope that's help !

The estimate for 679+294=1,000 <span />
The answer is C because its the only one that makes sense when you see what the question is asking you
The closest is D . But it should be + x^2 not - x^2
