expand x^2(cos(2x+3y)(2x+3))+sin(2x+3y)

expand

x^{2} (cos (2 x + 3 y) (2 x + 3)) + sin (2 x + 3 y)

2 x^{3} cos (2 x + 3 y) + 3 x^{2} cos (2 x + 3 y) + sin (2 x + 3 y)

Solution steps

x^{2} (cos (2 x + 3 y) (2 x + 3)) + sin (2 x + 3 y)

Remove parentheses:

(a) = a

= x^{2} cos (2 x + 3 y) (2 x + 3) + sin (2 x + 3 y)

Expand

x^{2} cos (2 x + 3 y) (2 x + 3) : 2 x^{3} cos (2 x + 3 y) + 3 x^{2} cos (2 x + 3 y)

= 2 x^{3} cos (2 x + 3 y) + 3 x^{2} cos (2 x + 3 y) + sin (2 x + 3 y)

(x - 1) (e^{x} + 3)

x^{2} (x d v + v d x)

\frac{A ( e ^{x} + 3 )}{e ^{x} - 1}

(x + y = z) (x + 2 x + z + 14)

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