Exercise 16 Page 73

We are asked to simplify the given expression. For this specific exercise, the negative sign can be thought of as - 1. Then we can use the Distributive Property to multiply the terms on the inside of the parentheses by the term on the outside, - 1.

-(-2+6t)

Rewrite

Rewrite negative sign as -1

- 1 (-2+6t)

Distr

Distribute - 1

(- 1) (-2) + (-1)( 6t)

MultNegNegTwoPar

(- a)(- b)=a* b

2+(-1)( 6t)

MultNegPos

(- a)b = - ab

2+(-6t)

AddNeg

a+(- b)=a-b

2-6t

Since 2 and 6t are not like terms, we cannot simplify the expression any further.
