simplify (b^2-64)/(8-b)

simplify

\frac{b ^{2} - 64}{8 - b}

- b - 8

Solution steps

\frac{b ^{2} - 64}{8 - b}

Factor

b^{2} - 64 : (b + 8) (b - 8)

= \frac{( b + 8 ) ( b - 8 )}{8 - b}

8 - b = - (b - 8)

= \frac{( b + 8 ) ( b - 8 )}{- ( b - 8 )}

Cancel the common factor:

b - 8

= \frac{b + 8}{- 1}

Apply the fraction rule:

\frac{a}{- 1} = - a

= - (b + 8)

Apply the distributive law:

- (a + b) = - a - b

- (b + 8) = - b - 8

= - b - 8

- 4 + 16

24 x^{2} + 2 x - 15

\frac{15 m ^{3} - 34 m ^{2} + 9 m + 10}{3 m - 5}

\frac{- 2 ( x ^{2} p ^{3} ) ^{- 1}}{3 x ^{10} p ^{- 1}}

\frac{1}{2} (\frac{2}{3})
