xa-xb= x(a-b)
Let y= ab+(- a)(b) +(-a)(-b) factor out -a y= ab+(-a){b+(-b)} y=ab+(-a)(0) y =ab -------------------(1) now factor out b y= b{a+(-a)}+(-a)(-b) y= b(0) +(-a)(-b) y= (-a)(-b)-----------------(2) equate (1) and (2) (-a)(-b)=ab minus x minus = positive
It is not clear what you mean by x^2 minus "factor x". Please add more information and resubmit.
x^3 - 36xFactoring out x from both the terms we get= x(x^2-36)Using the relationship, a^2 - b^2 = (a-b)(a+b) we get= x(x-6)(x+6)
(x + 2)(x - 9)
(x + 2)(x - 4)
(x - 5)(x + 3)
(b-c)(a+b)-ac
x(x + 3)(x - 4)
x(-b)=m(x-c)
(x + 1)(x - 8)
x(x-1)
(x - 2)(2x + 3)
