1) ax + bx + ac + bc = x(a + b) + c(a + b) = (c + x)(a + b)
2)4a +by + ay + 4b = 4a + 4b + ay + by = 4(a + b) + y(a + b) = (4 + y)(a + b)
3)px + py - 5x - 5y = p(x + y) - 5(x + y) = (p - 5)(x + y)
4)3a + 3a² - b - ab = 3a(1 + a) - b(1 + a) = (3a - b)(1 + a)
5)2x² - 3x + 4ax - 6a = x(2x - 3) + 2a(2x - 3) = (x + 2a)(2x - 3)
