(2a + b)(2c + d).
(2a + b)(2c + d)
(a + b)(b - 2c)
2bc + 8b - 3c - 12 is an expression, not an equation or inequality. It cannot, therefore have "an answer".
3a(b+c)+2b(b+c)
(a + 2b)(c + 2d)
(2a + b)(2c + d).
ac + 2ad + 2bc + 4bd = a(c + 2d) + 2b(c + 2d) = (a + 2b)(c + 2d) Now expand to confirm your answer: c(a + 2b) + 2d(a + 2b) = ac + 2bc + 2ad + 4bd ≡ ac + 2ad + 2bc + 4bd
(2a + b)(2c + d)
(2a + b)(2c + d)
(2a + b)(2c + d)
ac + 2ad + 2bc + 4bd (ac + 2ad) + (2bc + 4bd) group the figures a(c + 2d) + 2b(c + 2d) remove the common divisors of each set (a + 2b)(c + 2d) take the figures in parentheses as one set, and add the outside figures as the other
