y = 3x + 21x2 = 3x(1 + 7x)
x(4x-2)
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
(2x - 1)(x + 3)
The expression d squared plus 16d plus 48 can be factored as (d + 4)(d + 12).
2(x-32)(x+60)
It can not be factored because its discriminant is less than zero
It can't be factored because its discriminant is less than zero
(x - 8)(x - 6)
x(4x-2)
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
(2x - 1)(x + 3)
3y4 + 3y2 = 3y2(y2 + 1)
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.
