(a + 2b)(c + 2d)
(3x - 4)(2x^2 + 6x + 5)
6(ab - ac + b2 - bc)
The expression, as given, cannot be factorised.
6ab(2x2+x-5)
(x - 2)(2x - 3)
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
a(x + y - z)
x³ - x² + x - 3 (x² + 1)(x - 1) - 2
x2 - 9x + 20 = (x - 4)( x - 5)

Terms are in expressions that separate by plus or minus signs. The answer is TERMS.
x does not equal -1, because if x is minus 1, x plus 1 is zero and division by zero is not defined.
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9
