expand ((x+h)^2-1)/((x+h)+4)

expand

\frac{( x + h ) ^{2} - 1}{( x + h ) + 4}

\frac{x ^{2} + 2 x h + h ^{2} - 1}{x + h + 4}

Solution steps

\frac{( x + h ) ^{2} - 1}{( x + h ) + 4}

Remove parentheses:

(a) = a

= \frac{( x + h ) ^{2} - 1}{x + h + 4}

Expand

(x + h)^{2} - 1 : x^{2} + 2 x h + h^{2} - 1

= \frac{x ^{2} + 2 x h + h ^{2} - 1}{x + h + 4}

(e^{t} - e^{- t})^{3}

(2 x + 2Δ x + 3) (4 x - 5)

\frac{( x + 4 ) ( x + 8 )}{x + 5}

(2 + 1)^{n} (2 + 2)

\frac{( - 1 + r ^{3} ) ^{2}}{r ^{3}}
