expand 3left(2a+5a^2)+(2a-a^2)

expand

3 l e f t (2 a + 5 a^{2}) + (2 a - a^{2})

6 e l f t a + 15 e l f t a^{2} + 2 a - a^{2}

Solution steps

3 l e f t (2 a + 5 a^{2}) + (2 a - a^{2})

= 3 e l f t (2 a + 5 a^{2}) + (2 a - a^{2})

Expand

3 l e f t (2 a + 5 a^{2}) : 6 e l f t a + 15 e l f t a^{2}

= 6 e l f t a + 15 e l f t a^{2} + (2 a - a^{2})

Remove parentheses:

(a) = a

= 6 e l f t a + 15 e l f t a^{2} + 2 a - a^{2}

e^{e^{x} (x - 1)}

(7, 1) y (3, - 2)

x (1 - x^{4} + x - x^{9})

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

\frac{2}{( s ( s ^{2} + 5 s + 6 ) )}
