Plzz tell me the answer very important....plzzz
Step by step explanation....

Answer 1

Answer:

${y}^{2} + 18y + 65 \\ = {y}^{2} +13y + 5y + 65 \\ = y(y + 13) + 5(y + 13) \\ = (y + 13)(y + 5)$

Answer 2

Answer:

${y}^{2} + 18y + 65 = 0 \\ {y}^{2} + (13 + 5)y + 6 = 0 \\ {y}^{2} + 13y + 5y + 65 = 0 \\ y(y + 13) + 5(y + 13) = 0 \\ (y + 13)(y + 5) = 0 \\ y + 13 = 0 \: \: \: \: \: and \: \: \: \: y + 5 = 0 \\ y = - 13 \: and \: - 5$
