(7x + 7)(x + 2) = 7x2 + 21x + 14
x3 - 7x2 + 6x =x (x2 - 7x + 6) =x (x - 6) (x - 1)
21x2 + 27x - 30 = 3*(7x2 + 9x - 10) = 3*(7x2 - 5x + 14x - 10) =3*[x*(7x - 5) + 2*(7x - 5)] = 3*(7x - 5)*(x + 2)
7x2
Either: (7x + 4)(x + 4) = 7x2 + 32x + 16 or: (7x - 4)(x - 4) = 7x2 - 32x + 16
7x2 + 7x - 14 = 7(x2 + x - 2) = 7(x + 2)(x - 1)
(7x + 7)(x + 2) = 7x2 + 21x + 14
(x - 2)(7x + 15)
Are you seeking the factors? 7x2 - 10x + 3 = (x - 1)(7x - 3).
7x2-10x+3=0 (7x-3)(x-1)=0
There is no answer since what is given is an expression, not an equation. The expression is that of a parabola.
x3 - 7x2 + 6x =x (x2 - 7x + 6) =x (x - 6) (x - 1)
21x2 + 27x - 30 = 3*(7x2 + 9x - 10) = 3*(7x2 - 5x + 14x - 10) =3*[x*(7x - 5) + 2*(7x - 5)] = 3*(7x - 5)*(x + 2)
7x2
Either: (7x + 4)(x + 4) = 7x2 + 32x + 16 or: (7x - 4)(x - 4) = 7x2 - 32x + 16
7x2 -4x -5x2 +2x = 2x2 -2x
Factoring requires you to reduce as much as possible. To factor 7x + 49, you remove the common factor of 7x and 49, which is 7, and multiply (7x + 49)/7 (which is x + 7) by 7, without actually simplifying. 7x + 49 = 7(x + 7) Then, if possible, do the same thing until it cannot be further factored.
