Hope it would be helpful✌

Answer 2

Identity III:

$\large \purple {\sf {(x + a)(x + b) = {(x)}^{2} + (a + b)x + (ab)}}$

Given:

$\large \purple {\sf {(y + 3)(y + 5)}}$

Explanation:

$\large \purple {\sf {{(y)}^{2} + (3 + 5)y + (3)(5)}}$

$\large \purple {\sf { = {y}^{2} + 8y + 15}}$

Answer:

$\large \purple {\sf {(y + 3)(y + 5) = {y}^{2} + 8y + 15}}$
