simplify 22-9(x+3y)-(x+3y)^2

simplify

22 - 9 (x + 3 y) - (x + 3 y)^{2}

22 - 9 x - 27 y - x^{2} - 6 x y - 9 y^{2}

Solution steps

22 - 9 (x + 3 y) - (x + 3 y)^{2}

(x + 3 y)^{2} : x^{2} + 6 x y + 9 y^{2}

= 22 - 9 (x + 3 y) - (x^{2} + 6 x y + 9 y^{2})

Expand

- 9 (x + 3 y) : - 9 x - 27 y

= 22 - 9 x - 27 y - (x^{2} + 6 x y + 9 y^{2})

- (x^{2} + 6 x y + 9 y^{2}) : - x^{2} - 6 x y - 9 y^{2}

= 22 - 9 x - 27 y - x^{2} - 6 x y - 9 y^{2}

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

(x + x^{2})^{3}

\frac{4}{17} \div \frac{3}{16}

\frac{2 z ^{6}}{2 ( z ^{2} ) ^{2}}

(2 x^{- 1})^{2}
