2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
x2 + x2 = 2x2 2x^2
The number times itself. For example 2 squared = 2x2=4 so 2 squared =4
2x2+14x

2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
3x2 - 5x2 = -2x2
x2 + x2 = 2x2 2x^2
The number times itself. For example 2 squared = 2x2=4 so 2 squared =4
4. 2x2=4
2x2+14x

The GCF is 2x2
2x2 + x2 = 3x2

17 squared times 2 squared (17^2x2^2) (17x17x2x2)
x2 - (2x)2 = x2 - 4x2 = -3x2 x2 - 2x2 = -x2
