Answer 1

Question: 1

$- 2 a ^ { 2 } + 5 p + 4 c d$

Answer:

$5p+4cd-2a^{2}$

Question: 2

$\frac { 2 } { 3 } x ^ { 2 } - \frac { 3 } { 7 } y + 7$

Answer:

${ \boxed{ \tt{ \red{\frac{14x^{2}-9y+147}{21}}}}} \\ \\ \sf solution \implies \\ \\ { \overbrace{\frac { 2 } { 3 } x ^ { 2 } - \frac { 3 } { 7 } y + 7}} \\ \\ \tt Factor \: out \: \frac{1}{21}. \\ \\ \tt hence \: \frac{14x^{2}-9y+147}{21} \\ \\{\underbrace{ \sf then \: \frac{2x^{2}}{3}-\frac{3y}{7}+7 \: \blue \: answer}}$
