Question

(y+3)^2+5(y+3)-24 plz solve this​

Answer 1

Answer:

y² + 11y

Step-by-step explanation:

( y + 3 )²

Formula : -

( a + b )² = a² + b² + 2ab

Here,

a = y

b = 3

( y + 3 )² = y² + 9 + 6y

5 ( y + 3 ) = 5y + 15

( y + 3 )² + 5 ( y + 3 ) - 24

= y² + 9 + 6y + 5y + 15 - 24

= y² + 6y + 5y + 9 + 15 - 24

= y² + 11y + 24 - 24

= y² + 11y
