4-71.

Factor each expression in parts (a) and (b). Then, in parts (c) and (d), factor and simplify each expression. Homework Help ✎

1. bx + ax

2. x + ax

3. $\frac { a x + a } { x ^ { 2 } + 2 x + 1 }$

4. $\frac { x ^ { 2 } - b ^ { 2 } } { a x + a b }$

x(b + a)

$\frac{\textit{a}(\textit{x}+1)}{(\textit{x}+1)^{2}}$

x(1 + a)

$\frac{(\textit{x}+\textit{b})(\textit{x}-\textit{b})}{\textit{a}(\textit{x}+\textit{b})}$
