expand ((x+7)(x+3))/(x+4)

expand

\frac{( x + 7 ) ( x + 3 )}{x + 4}

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

Solution steps

\frac{( x + 7 ) ( x + 3 )}{x + 4}

Expand

(x + 7) (x + 3) : x^{2} + 10 x + 21

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

\frac{x ( x + 1 )}{2} + (k + 1)

\frac{6}{s ( 0.2 s + 1 ) + 6}

\frac{2 x + 4 x - 3}{x ^{2}}

- 2 (5 ln (2) - 2)

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