3y4 + 3y2 = 3y2(y2 + 1)
It can't be factored because its discriminant is less than zero
(x - 8)(x - 6)
x(4x-2)
(2x - 1)(x + 3)
Yes, it can. ANY equation of this form can be factored. The factors may not be integers or even real numbers, though.
The expression d squared plus 16d plus 48 can be factored as (d + 4)(d + 12).
2(x-32)(x+60)
x2 + 7x - 56 cannot be factorised.
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
It is (x-1)(x-8) when factored
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
X2 - 8X + 15 = (X - 3)(X - 5)
