$\large\bf{To~simplify:}$

$\bf 3x(3y - x) + 2x(2y + x) + x(y - z) \\ \bf = (9xy - {3x}^{2} ) + (4xy + {2x}^{2} ) + (xy - xz) \\ \bf Grouping \: all \: the \: like \: terms, \: we \: get: \\ \bf (9xy + 4xy + xy) + ( {2x}^{2} - {3x}^{2} ) - xz \\ \bf = \underline{ \underline{14xy - {x}^{2} - xz}}$

Answer 2

Answer:

14xy-x²-xz

Step-by-step explanation:

3x(3y-x)+2x(2y+x)+x(y-z)

9xy-3x²+4xy+2x²+xy-xz

13xy-x²+xy-xz

14xy-x²-xz
