expand (x-9\circ x^2)*4

expand

(x - 9 \circ x^{2}) \cdot 4

- 36 \circ x^{2} + 4 x

Solution steps

(x - 9 \circ x^{2}) \cdot 4

= 4 (x - 9 \circ x^{2})

Apply the distributive law:

a (b - c) = ab - a c

a = 4, b = x, c = 9 \circ x^{2}

= 4 x - 4 \cdot 9 \circ x^{2}

Simplify

4 x - 4 \cdot 9 \circ x^{2} : - 36 \circ x^{2} + 4 x

= - 36 \circ x^{2} + 4 x

\frac{e ^{- 2 + 2} ( 6 - 4 2 )}{49}

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

\frac{6 x ^{2} - x - 136}{( x - 5 ) ( x + 4 )}

(2, 0, - 2) y (3, - 3, 0)

\frac{ab ( a ^{4} + b ^{4} )}{a ^{6} + b ^{6}}
