$$ x x = x^{1 + 1} = x^2 $$

Multiply each term of $ \left( \color{blue}{6-4x}\right) $ by each term in $ \left( -5x^2-32\right) $.

$$ \left( \color{blue}{6-4x}\right) \cdot \left( -5x^2-32\right) = -30x^2-192+20x^3+128x $$Multiply $ \color{blue}{29} $ by $ \left( x-1\right) $ $$ \color{blue}{29} \cdot \left( x-1\right) = 29x-29 $$

Multiply each term of $ \left( \color{blue}{29x-29}\right) $ by each term in $ \left( x^2+3\right) $.

$$ \left( \color{blue}{29x-29}\right) \cdot \left( x^2+3\right) = 29x^3+87x-29x^2-87 $$

Remove the parentheses by changing the sign of each term within them.

$$ - \left( 29x^3+87x-29x^2-87 \right) = -29x^3-87x+29x^2+87 $$

Combine like terms:

Multiply each term of $ \left( \color{blue}{-9x^3-x^2+41x-105}\right) $ by each term in $ \left( 2x-3x^2\right) $.

$$ \left( \color{blue}{-9x^3-x^2+41x-105}\right) \cdot \left( 2x-3x^2\right) = -18x^4+27x^5-2x^3+3x^4+82x^2-123x^3-210x+315x^2 $$

Combine like terms:

$$ \color{blue}{-18x^4} +27x^5 \color{red}{-2x^3} + \color{blue}{3x^4} + \color{green}{82x^2} \color{red}{-123x^3} -210x+ \color{green}{315x^2} = \\ = 27x^5 \color{blue}{-15x^4} \color{red}{-125x^3} + \color{green}{397x^2} -210x $$
