expand ((x+7)(x-3))/((x-5)^2)

expand

\frac{( x + 7 ) ( x - 3 )}{( x - 5 ) ^{2}}

\frac{x ^{2} + 4 x - 21}{x ^{2} - 10 x + 25}

Solution steps

\frac{( x + 7 ) ( x - 3 )}{( x - 5 ) ^{2}}

(x - 5)^{2} = x^{2} - 10 x + 25

= \frac{( x + 7 ) ( x - 3 )}{x ^{2} - 10 x + 25}

Expand

(x + 7) (x - 3) : x^{2} + 4 x - 21

= \frac{x ^{2} + 4 x - 21}{x ^{2} - 10 x + 25}

x^{3}

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

(- 2, 3) y (8, - 5)

δ (x - x)

(4 + i)^{4}
