expand (2x^2+1)/((x-3)(5x+a))

expand

\frac{2 x ^{2} + 1}{( x - 3 ) ( 5 x + a )}

\frac{2 x ^{2} + 1}{5 x ^{2} + a x - 15 x - 3 a}

Solution steps

\frac{2 x ^{2} + 1}{( x - 3 ) ( 5 x + a )}

Expand

(x - 3) (5 x + a) : 5 x^{2} + a x - 15 x - 3 a

= \frac{2 x ^{2} + 1}{5 x ^{2} + a x - 15 x - 3 a}

(e^{x} - e^{- x})^{2}
