3x2-39x-90 = (3x+6)(x-15) when factored
3x2+7-6 = (3x-2)(x+3) when factored
y = 3x + 21x2 = 3x(1 + 7x)
This quadratic expression can't be factored because its discriminant is less than zero.
6x2-17x+7 = (2x-1)(3x-7) when factored

3x2-39x-90 = (3x+6)(x-15) when factored
x2+x-6 = (x-2)(x+3) when factored
2x2 + 3x + 1 = (x + 1)(2x + 1)
3x2+7-6 = (3x-2)(x+3) when factored
It is a quadratic expression and can be factored into: (3x+1)(x+2)
y = 3x + 21x2 = 3x(1 + 7x)
x2 + 3x - 28 = x2 + 7x - 4x - 28 = x(x + 7) - 4(x + 7) = (x + 7)(x - 4)
6y2+17y-14 = (2x+7)(3x-2) when factored
If you mean: 3x^2 +31x +36 then it is (3x+4)(x+9) when factored
2x(3x + 5)
