x² + 4x + 45​

Answer 1

Answer:

HEY BUDDY HOPE IT HELPS YOU

Step-by-step explanation:

Q. Factorise x² + 4x + 45 .

Hey buddy the given equation is wrong , it should be x² + 4x - 45 because the above equation cannot be solved as it breaks on between due to

some reasons of signs of positive ( + ) and negative ( - ) .

So , the equation is

x² + 4x - 45 = 0

By , splitting the middle term

x² + 9x - 5x - 45 = 0

Making the factors ,

x ( x + 9 ) - 5 ( x + 9 ) = 0

We get,

( x + 9 ) ( x - 5 ) = 0

Therefore , x = - 9 or x = 5 .

Hence , the equation x² + 4x - 45 has two factor which are ( - 9 ) and ( 5 ) .
