expand ((6a+7b)(a-7b))/(b(6ab+7))

expand

\frac{( 6 a + 7 b ) ( a - 7 b )}{b ( 6 ab + 7 )}

\frac{6 a ^{2} - 35 ab - 49 b ^{2}}{6 a b ^{2} + 7 b}

Solution steps

\frac{( 6 a + 7 b ) ( a - 7 b )}{b ( 6 ab + 7 )}

Expand

b (6 ab + 7) : 6 a b^{2} + 7 b

= \frac{( 6 a + 7 b ) ( a - 7 b )}{6 a b ^{2} + 7 b}

Expand

(6 a + 7 b) (a - 7 b) : 6 a^{2} - 35 ab - 49 b^{2}

= \frac{6 a ^{2} - 35 ab - 49 b ^{2}}{6 a b ^{2} + 7 b}

t (x = 5 t + 3)

\frac{5 e ^{- s}}{( 30 s + 1 ) s}

\frac{8}{( x + a ) ( x + b )}

(1.5 - 0.8 x) d y

(2 x + 3 y) e^{3}
