Factoring By Grouping (#1)
By C Gulliksen
Choose the best factorization for each polynomial.
a(x - 3) + 2(x - 3)
5x(x +2) + 7(x + 2)
x(x + 2) + 7(x + 2)
a(2a - 7) + 5(2a - 7)
(3a + 2) + 6a(3a + 2)
(m-3)-2m(m-3)
6b(a - 7) + (a - 7)
3r(r + 2) + (r + 2)
y(2 - x) - (2 - x)
8a(a - b) - (a - b)
4(3s - t) + u(3s - t) - 2r(3s - t)
