ab-2ac+b^2-2bc
You want: abc + ab Factor out the common terms which are "a" and "b" ab ( c + 1 )
(a + b)(b + c)
(a + 3)( b + 2)
x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
ab + 4 + a + 4b factors to (a + 4)(b + 1)
The GCF is a.
a(b+3)+b(b+3)
(a - c)(b - d)
(a + b)(b - 2c)
(a + b)(b - 2c)
(a+b)(a squared-ab+b squared)
