64-x2 = (8-x)(8+x) when factored
2 squared simply means two times itself, or in other words, 2*2
16 - y2 = (4 - y)*(4 + y)
x(4x-2)
x2 - 2x = x(x - 2)
64-x2 = (8-x)(8+x) when factored
2 squared simply means two times itself, or in other words, 2*2
(x - 8)(x - 6)
16 - y2 = (4 - y)*(4 + y)
x(4x-2)
x2 - 2x = x(x - 2)
It can't be factored because its discriminant is less than zero
3y4 + 3y2 = 3y2(y2 + 1)
(4+x) (2x-3)
(2x - 1)(x + 3)
Im assuming the "6x2" is supposed to be 6x squared. The factored form would be (2x+1) (3x-8)
Well x squared could can be broken down (factored) into x times x. So yes, it can be.
