Factor out a 2
2(X2 + X - 12)
2(X - 3)(X + 4)
===========
x(4x-2)
(2x - 1)(x + 3)
2(x-32)(x+60)
(a - 2b)(2a - b)
2(x - 3)(x - 3)
x(4x-2)
(2x - 1)(x + 3)
2(x-32)(x+60)
x2 + 7x - 56 cannot be factorised.
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
(a - 2b)(2a - b)
9x^(2) + 16 DOES NOT factor. Remember ; two squared terms with a plus(+) between them DOES NOT factor However, two squared terms with a minus(-) between them DOES factor . Hence 9x^(2) + 16 = (3x)^2) + 4^(2) does NOT factor However, 9x^(2) - 16 = (3x)^2) - 4^(2) does factor to ( (3x - 4)(3x + 4) Note the two different signs.
2s2+7s-15 = (2s-3)(s+5) when factored
6x2 + 5x - 6 is factored out to (2x + 3)(3x - 2).
It is: (x-2)(x-7) when factored
That can be factored to (x - 2)(x - 1)
2(x - 3)(x - 3)
