Question

(Y+3)(y-3)-y(y+5) is equal to 6

Answer 1

Solution :

(y+3)(y-3) - y(y+5) = 6

=> ( y² - 3² ) - y² - 5y = 6

=> y² - 9 - y² - 5y = 6

=> -5y = 6 + 9

=> -5y = 15

=> y = 15/(-5)

=> y = -3

Answer 2

here is ur answer:





$(y + 3)(y - 3) - y(y + 5) = 6 \\ \\ {y}^{2} - {3}^{2} - {y}^{2} - 5y =6 \\ \\ - 9 - 5y = 6 \\ \\ 5y = - 9 - 6 \\ \\ 5y = - 15 \\ \\ y = - \frac{15}{5} \\ \\ y = - 3$




hope it helps you!
