Factorise the following
x²-12x+32

( x − 4 ) ( x − 8 )   is the factorised form of the expression.

Step-by-step explanation:

x

−

12

x

+

32

We can Split the Middle Term of this expression to factorise it.

In this technique, if we have to factorise an expression like  

a

x

2

+

b

x

+

c

, we need to think of 2 numbers such that:

N

1

⋅

N

2

=

a

⋅

c

=

1

⋅

32

=

32

AND

N

1

+

N

2

=

b

=

−

12

After trying out a few numbers we get:

N

1

=

−

8

and  

N

2

=

−

4

(

)

⋅

(

)

=

, and

(

)

(

)

=

is a common factor to each of the terms.

is the factorised form of the expression.
