3x2(x2 - 3)
This is an expression and you do not solve an expression, but you can factor this one.X2 + 3X4X2(1 + 3X2)========
(3x + 1)(x + 5)
3 * x * x * y
3x2 + 6x is ONE expression. A common factor is a factor that is COMMON to two (or more) expressions - not just one. An alternative answer: 3x can be factored out of both of those.
3x2 + 48 + 192 = 3x2 + 240 = 3 (x2+ 80)
3(x + 7)(x - 8)
3(0)^2+7(x)-12 = -12
8
The expression does not have any real binomial factors. x is a monomial factor, and the other two involve complex numbers.
While it is possible to factor 3x2 from both of these and get 3x2(4 - 1), it's a lot easier to subtract 3x2 from 12x2 and get 9x2
factor out a 3x 3x(x-3)=3x2-9x
