Q.3
Find the product of (5p² + 4p + 7) and (p +2)​

Answer 1

$\large{\red{\mathfrak{\underline{Your~Answer:}}}}$

$\rightarrow \: (5 {p}^{2} + 4p + 7) \times (p + 2)$

$\rightarrow \: p(5 {p}^{2} + 4p + 7) + 2(5 {p}^{2} + 4p + 7)$

$\rightarrow \: {5p}^{3} + 4 {p}^{2} + 7p + 10 {p}^{2} + 8p + 14$

$\bold{\rightarrow \: {5p}^{3} + 14 {p}^{2} + 15p + 14}$
