Distributive property with variables (Full video)

Khan Academy

Supporting grades: 7

Description: Learn how to apply the distributive property to algebraic expressions. So, I'm gonna take, and lemme color code it, too, just for fun, so it's going to be 1/2 times, give myself some space, 1/2(2a-6b), so, 2a-6b, minus six, lemme write it this way - 6b, and then we have plus eight. So, 1/2 times 2a, so this is going to be 1/2 times 2a, times, lemme do it in that same color so you see where the 2a came from. 1/2(6) is going to be three, and then you still are multiplying times B.
