expand 1/(((x+h)+3)^2)

expand

\frac{1}{( ( x + h ) + 3 ) ^{2}}

\frac{1}{2 x h + x ^{2} + 6 x + h ^{2} + 6 h + 9}

Solution steps

\frac{1}{( ( x + h ) + 3 ) ^{2}}

Remove parentheses:

(a) = a

= \frac{1}{( x + h + 3 ) ^{2}}

(x + h + 3)^{2} = 2 x h + x^{2} + 6 x + h^{2} + 6 h + 9

= \frac{1}{2 x h + x ^{2} + 6 x + h ^{2} + 6 h + 9}

2 e^{j (\frac{π}{4} + π)}

(e^{x} + e^{- x})^{8}

\frac{- x + 1}{x ( x + 1 )}

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

cos (2) (t + \frac{π}{2})
