Question

Simplify the rational expression. State any restrictions on the variable.

Answer 1

factor the numerator:\[\frac{ (t+4)(t-8) }{ t-8 }\] eliminate like terms: \[t+4\]
restrictions:
look at original equation. Denominator cannot = 0.
To find restriction set t - 8 = 0 and solve for t.
t = 8 (restriction)

Answer 2

t+4,t=8
