Question

x raised to 4 - a raised to 4 divided by x raised to 1 - a raised to 1

Answer 1

$\frac{ {x}^{4} - {a}^{4} }{ {x}^{1} - a {}^{1} } \\ \frac{(x {}^{2} - a {}^{2})(x {}^{2} + a {}^{2} ) }{x - a} \\ \frac{(x - a)( x+ a)( {x}^{2} + {a}^{2}) }{x - a} \\ (x + a)( {x}^{2} + a {}^{2} ) \\ {x}^{3} + x {a}^{2} + a {x}^{2} + {a}^{3}$
