simplify ((x^4-y^4))/((x-y))

simplify

\frac{( x ^{4} - y ^{4} )}{( x - y )}

(x^{2} + y^{2}) (x + y)

Solution steps

\frac{x ^{4} - y ^{4}}{x - y}

x^{4} = (x^{2})^{2}

y^{4} = (y^{2})^{2}

= \frac{( x ^{2} ) ^{2} - ( y ^{2} ) ^{2}}{x - y}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

(x^{2})^{2} - (y^{2})^{2} = (x^{2} + y^{2}) (x^{2} - y^{2})

= \frac{( x ^{2} + y ^{2} ) ( x ^{2} - y ^{2} )}{x - y}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

x^{2} - y^{2} = (x + y) (x - y)

= \frac{( x ^{2} + y ^{2} ) ( x + y ) ( x - y )}{x - y}

Cancel the common factor:

x - y

= (x^{2} + y^{2}) (x + y)

\frac{x}{a ^{2} - a x} + \frac{1}{a} + \frac{1}{x}

\frac{4}{6 - 2}

3 x (x - 3)

3 x (x + 5)
