simplify (4/((x^2-x-30)))/(2/((x^2+x-42)))

simplify

\frac{\frac{4}{( x ^{2} - x - 30 )}}{\frac{2}{( x ^{2} + x - 42 )}}

\frac{2 ( x + 7 )}{x + 5}

Solution steps

\frac{\frac{4}{x ^{2} - x - 30}}{\frac{2}{x ^{2} + x - 42}}

Apply the fraction rule:

\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a \cdot d}{b \cdot c}

= \frac{4 ( x ^{2} + x - 42 )}{( x ^{2} - x - 30 ) \cdot 2}

Cancel

\frac{4 ( x ^{2} + x - 42 )}{( x ^{2} - x - 30 ) \cdot 2} : \frac{2 ( x + 7 )}{x + 5}

= \frac{2 ( x + 7 )}{x + 5}
