Answer 1

Given Question:-

14x + 10y -12xy - 13xy , 18 - 7x - 10y + 8xy, 4xy

Solution:-

$\begin{gathered}:\implies\sf{14x + 10y -12xy - 13xy , 18 - 7x - 10y + 8xy, 4xy}\\\\\: :\implies\sf{14xy + 10y - 12xy - 13 + 18 -7x - 10y + 8xy + 4xy}\\\\\: :\implies \sf{14x - 7x + {\cancel {10y}} -{\cancel{10y}} -12 + 8xy + 4xy -13-18}\\\\ :\implies\sf{7x - {\cancel{12xy }}+ {\cancel{12xy }}- 5 }\\\\ :\implies \sf{7x + 5}\end{gathered}$

Given Question:-

3p²q² - 4pq + 5, - 10p²q², 15 + 9PM + 7p²q²

Note:-

Before Answering I want to say Your Question have a Typo. I think It should be 9pq instead of 9PM .

Solution:-

$\begin{gathered}\sf{3p²q² - 4pq + 5, - 10p²q², 15 + 9pq + 7p²q²}\\\\:\implies\sf{3p²q²-4pq +5-10p²q²+15+9pq+7p²q²}\\\\:\implies\sf{3p²q² + 7p²q² - 10p²q² - 4pq + 9pq + 5 + 15}\\\\:\implies \sf{ {\cancel{10p²q²}}- {\cancel{10p²q²}}+5pq+20}\\\\:\implies \sf{5pq + 20 }\end{gathered}$
