Question

(p + 5)² + 2(p + 5)​

Answer 1

${(p + 5)}^{2} + 2(p + 5)$

We know that;

$\blue{ \boxed{ (a + b)^{2} = a^{2} + 2(a)(b) + b^{2} }}$

$\implies {p}^{2} + 2(p)(5) + {5}^{2} + 2(p + 5)$

$\implies {p}^{2} + 10p + 25 + 2p + 10$

$\orange{ \boxed{ \therefore {(p + 5)}^{2} + 2(p + 5) = {p}^{2} + 12p + 35 }}$

HOPE THAT HELPS!!
