Solve a^2-2ab-3b^2/a^2-6ab-7b^2

$$\frac { a ^ { 2 } - 2 a b - 3 b ^ { 2 } } { a ^ { 2 } - 6 a b - 7 b ^ { 2 } }$$

Evaluate

$$\frac{a-3b}{a-7b}$$

Short Solution Steps

Factor the expressions that are not already factored.

$$\frac{\left(a+b\right)\left(a-3b\right)}{\left(a+b\right)\left(a-7b\right)}$$

Cancel out a+b in both numerator and denominator.

$$\frac{a-3b}{a-7b}$$

Expand

$$\frac{a-3b}{a-7b}$$
