Exercise 2 Page 53

Be careful of negatives when distributing.

-14a+6b

Practice makes perfect

We will begin simplifying by distributing the -4 and the -2 to the terms inside the parentheses.

- 4(3a+b) -2(a-5b)

Distribute -4 & - 2

3a(- 4)+b(- 4) +a(- 2)-5b(- 2)

a(- b)=- a * b

-3a( 4)-b(4)-a(2)-5b(- 2)

MultNegNegOnePar

- a(- b)=a* b

-3a( 4)-b(4)-a(2)+5b(2)

Multiply

-12a-4b-2a+10b

Add and subtract terms

-14a+6b

Since - 14a and 6b are not like terms, the expression cannot be simplified further.
