Combining like terms with distribution (Full video)

Khan Academy

Supporting grades: 6

Description: Learn to expand and simplify an expression like 3(5x+6) + (7x+2)*4. You're gonna have to do some distribution and then some combining of like terms. So as I mentioned, when I see this three times the entire expression 5x plus six, I want to distribute that three. So this part of the expression we have now simplified to 15x plus 18.
