(x2 + 1)(x2 - 2)
2x to the fourth power minus 162 equals -146
No.
x cubed minus 216
There is a formula for the "difference of squares." In this case, the answer is (x2 - 5)(x2 + 5)
(x2 - 2)(x2 + 2)
(x2 + 1)(x2 - 2)
2x to the fourth power minus 162 equals -146
x^2(x - 4)(x + 4)
No.
x cubed minus 216
3x^3(x - 4)
(3x^2 - 4y^2)(3x^2 + 4y^2)
1x to the power of 4
4(10x4 + 3)(10x4 - 3)
So x4 - 1 is the difference of squares, so x4 - 1 = (x2 - 1)(x2 + 1) = (x + 1)(x - 1)(x2 + 1).
There is a formula for the "difference of squares." In this case, the answer is (x2 - 5)(x2 + 5)
