Question

Simplify 3x (3y_x) + 2x (2y+x) +x (y _x)
Step by step explanation ​

Answer 1

Step-by-step explanation:

$\sf Given\begin{cases}\sf {3x (3y-x)+2x (2y+x)+x (y-x)} \\ \longrightarrow\sf {9xy-3x {}^{2}+2xy+2x {}^{2}+xy-0} \\ \longrightarrow\sf {9xy+2xy+xy-3x {}^{2}+2x{}^{2}} \\ \longrightarrow \sf {11xy+xy-x {}^{2}} \\ \longrightarrow{\underline{\boxed {\bf {-x {}^{2}+12xy}}}}\end {cases}$

Answer 2

Answer:

12xy - x²............
