Question

evaluate quaadritic equation x^2+5x+6=0

Answer 1

Hello ☺️❤️

_______________________

x² + 5x + 6 = 0

⇒ x² + 2x + 3x + 6 = 0

⇒ x ( x + 2 ) + 3 ( x + 2 ) = 0

⇒ ( x + 2 ) ( x + 3 ) = 0

Here,

x + 2 = 0
⇒ x = - 2

And,

x + 3 = 0
⇒ x = - 3

Answer 2

Hello friends!!

Here is your answer :

=> x² + 5x + 6 = 0

Method 1 : BY FACTORISATION

x² + 5x + 6 = 0

x² + 3x + 2x + 6 = 0

x ( x + 3 ) + 2 ( x + 3 ) = 0

( x + 3 ) + ( x + 2 ) = 0

x = - 3 or - 2
