Question 116084: Simplify
-10(2a - 6b)
Answer by bucky(2189)   (Show Source):
You can put this solution on YOUR website! This problem is of a type called distributed multiplication. It tells you to multiply each
of the terms in the set of parentheses by -10
.
When you multiply -10 times 2a you multiply the two numbers together and multiply that by
the variable a. So to get -10 times 2a you multiply -10 times 2 to get -20 and you multiply that
by "a". So the first multiplication in this problem is -10*2a = -20a.
.
Next you multiply -10 times -6b following the same process ... multiply the two numbers and
multiply that result times b. The -10 times the -6 equals +60 (remember that when you multiply
two numbers that both have the same sign, the answer is positive). Then you multiply that
result by b to get the answer of +60b.
.
Putting these two multiplications together results in:
.
-10(2a - 6b) = -20a + 60b
.
Hope this helps you to see how to do a distributed multiplication.
