7x2 + 7x - 14 = 7(x2 + x - 2) = 7(x + 2)(x - 1)

(7x + 7)(x + 2) = 7x2 + 21x + 14

Are you seeking the factors? 7x2 - 10x + 3 = (x - 1)(7x - 3).

7x2

There is no answer since what is given is an expression, not an equation. The expression is that of a parabola.

7x2-10x+3=0 (7x-3)(x-1)=0

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)

Either: (7x + 4)(x + 4) = 7x2 + 32x + 16 or: (7x - 4)(x - 4) = 7x2 - 32x + 16

7x2 - 14x = 7x(x - 2)

Add 1 to both sides. 7x2 - 8x + 1 = 0 factors to (x - 1)(7x - 1) x = 1, 1/7 Check it. 7 - 8 + 1 = 0 7/49 - 56/49 + 49/49 = 0 It checks.

(7x + 2)(x - 3)
