Factorise x^2-25x+66 by mid term splitting method
  • 1 answers

Yogita Ingle 4 years, 4 months ago

Let's rewrite this expression as: x2 -25x +66
The middle term needs to be split into two terms whose product is +66x2 while the sum remains -25x
 x2 - 22x  - 3x  +66
= x(x - 22) - 3 (x - 22)
= (x - 22) (x - 3)
