expand (9e^x-7)(8e^x)

expand

(9 e^{x} - 7) (8 e^{x})

72 e^{2 x} - 56 e^{x}

Solution steps

(9 e^{x} - 7) (8 e^{x})

Apply the distributive law:

a (b - c) = ab - a c

a = (8 e^{x}), b = 9 e^{x}, c = 7

= (8 e^{x}) \cdot 9 e^{x} - (8 e^{x}) \cdot 7

= 9 e^{x} (8 e^{x}) - 7 (8 e^{x})

Simplify

9 e^{x} (8 e^{x}) - 7 (8 e^{x}) : 72 e^{2 x} - 56 e^{x}

= 72 e^{2 x} - 56 e^{x}

\frac{( s + 1 ) ( s + 2 )}{( s + 3 ) ^{2} ( s + 4 )}

(2 x^{2} (x^{3} + y^{4}) + 3 x^{2}) e^{x^{3} + y^{3}}

y (y - 1) d x + (x - y^{2}) d y

(l^{3} o^{4} v^{5} - 6 e^{3}) (l^{3} o^{4} v^{5} + 6 e^{3})

\frac{9 ( a - 2 )}{2 a + 4}
