expand (3-3x-3/2 y)^2

expand

(3 - 3 x - \frac{3}{2} y)^{2}

9 x y - 18 x + 9 x^{2} - 9 y + \frac{9 y ^{2}}{4} + 9

Solution steps

(3 - 3 x - \frac{3}{2} y)^{2}

Multiply

\frac{3}{2} y : \frac{3 y}{2}

= (3 - 3 x - \frac{3 y}{2})^{2}

(3 - 3 x - \frac{3 y}{2})^{2} = (3 - 3 x - \frac{3 y}{2}) (3 - 3 x - \frac{3 y}{2})

= (3 - 3 x - \frac{3 y}{2}) (3 - 3 x - \frac{3 y}{2})

Expand

(3 - 3 x - \frac{3 y}{2}) (3 - 3 x - \frac{3 y}{2}) : 9 x y - 18 x + 9 x^{2} - 9 y + \frac{9 y ^{2}}{4} + 9

= 9 x y - 18 x + 9 x^{2} - 9 y + \frac{9 y ^{2}}{4} + 9

\frac{x ^{4} - 4 x ^{3} + 6 x ^{2} - ( m + 2 ) x + n + 3}{x ^{2} + 2 x + 1}

\frac{2 x ^{2} + 17 x - 21}{( x + 5 ) ( x + 1 ) ( x - 2 )}

\frac{7}{( x - 1 ) ^{2}}

, (6 - 2 x) (20 - 2 x)

\frac{( 9 \cdot x + 6 )}{( x + 3 ) \cdot x \cdot ( x - 4 )}
