(x2 + 7x - 18) = (x + 9)(x - 2)
If that was 2x^2 + 5x + 2, it would factor to (2x + 1)(x + 2)
14x2 + 29x - 15= 14x2 + 35x - 6x - 15= 7x(2x + 5) - 3(2x + 5)= (2x + 5)(7x - 3)
It's just a mathematical polynomial: 7x + 3y.
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
7x2 plus 7x5 = 49
(7x + 7)(x + 2) = 7x2 + 21x + 14
There is no answer since what is given is an expression, not an equation. The expression is that of a parabola.
Either: (7x + 4)(x + 4) = 7x2 + 32x + 16 or: (7x - 4)(x - 4) = 7x2 - 32x + 16
21x2 + 27x - 30 = 3*(7x2 + 9x - 10) = 3*(7x2 - 5x + 14x - 10) =3*[x*(7x - 5) + 2*(7x - 5)] = 3*(7x - 5)*(x + 2)
(x - 3)(7x + 2)
(7x + 4)(x - 5)
(7x + 6)(x - 2)
(7x + 4)(x - 1)
I suppose you mean, how do you factor it. 7x2 - 9x - 10 = (7x + 5)(x - 2).
(7x + 5)(x - 2)
Are you seeking the factors? 7x2 - 10x + 3 = (x - 1)(7x - 3).
