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

simplify

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

- 8 - y

Solution steps

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

Factor

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

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

(8 + y) (8 - y) = - (8 + y) (y - 8)

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

Cancel the common factor:

y - 8

= - (8 + y)

Apply the distributive law:

- (a + b) = - a - b

- (8 + y) = - 8 - y

= - 8 - y

327 \cdot 27

\frac{x ^{4} - 4096}{x - 8}

x^{2} + 1 \times x^{2} + 1

y^{2} y
