No.109 Distribute and Combine Like Terms
POINT
Use the distributive property to remove parentheses, then combine like terms.
Simplify the following expressions.
Example
\(3(2a+4b)+5(a-3b)\)
\(2(3x-4y)-3(5x-y)\)
① \(11a-3b\)
② \(-9x-5y\)
② \(-9x-5y\)
Try it yourself.
Simplify the following expressions.
PRACTICE 01
\(2(3a+b)+4(a-2b)\)
\(10a-6b\)
PRACTICE 02
\(5(2x-y)-2(3x+4y)\)
\(4x-13y\)
PRACTICE 03
\(4(2a-b)-3(a+2b)\)
\(5a-10b\)
PRACTICE 04
\(3(4x+y)+2(x-5y)\)
\(14x-7y\)
PRACTICE 05
\(-2(3m-n)+5(m+2n)\)
\(-m+12n\)
PRACTICE 06
\(6(p-2q)-4(2p-q)\)
\(-2p-8q\)
