Question

x*x-22x-104 factorise it

Answer 1

Hey friend,hope this answer of mine helps you...............................

x²-22x-104

Lets factorise 104,

104 can either be written as

• 2*52 or
• 4*26

In the 1st case,52-2≠104

In the 2nd case,26-4=22

Hence,getting the desired.

By this condition the equation can be written as

x²+4x-26x-104

⇒x(x+4) -26(x+4)

by this, conclusion:

1)x-26=0

⇒x=26

2)x+4=0

⇒x=-4
