Answer 2

Question :

Factorise. p²-7p +12

Answer :

The factorization of the expression p²-7p +12 is ( p-4 ) ( p-3 )

Given :

The expression p²-7p +12

To find :

To factorise the given expression

Solution :

The given expression p²-7p +12 need to be middle term factorized.

= p² -3p - 4p + 12 [ Splitting the middle term by the factors of (12×1)=12 ]

= p ( p - 3 ) - 4 ( p - 3 ) [ Taking the common terms together ]

= ( p-4 ) ( p-3 )

Hence, the factorization of the expression p²-7p +12 is ( p-4 ) ( p-3 )
