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}

(x + x Δ)^{2}

\frac{1}{s ( s ^{2} + 7 )}

a (x + Δ x)^{2}

2 (3 x + 4 y = - 12)

R e (x + \frac{1}{x})^{4}
