Answer:

\mathrm{Simplify}\:\frac{a^4-b^4}{a-b}:\quad \left(a^2+b^2\right)\left(a+b\right)

Step-by-step explanation:

\frac{a^4-b^4}{a-b}

=\frac{\left(a^2\right)^2-\left(b^2\right)^2}{a-b}

\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)

\left(a^2\right)^2-\left(b^2\right)^2=\left(a^2+b^2\right)\left(a^2-b^2\right)

=\frac{\left(a^2+b^2\right)\left(a^2-b^2\right)}{a-b}

\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)

a^2-b^2=\left(a+b\right)\left(a-b\right)

=\frac{\left(a^2+b^2\right)\left(a+b\right)\left(a-b\right)}{a-b}

\mathrm{Cancel\:the\:common\:factor:}\:a-b

=\left(a^2+b^2\right)\left(a+b\right)
