(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

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)
