Question

Factorise the following using suitable identities. 1.X2-2x+1. 2.9x2-6x+1. 3.X2-(y+z)2

Answer 1

Step-by-step explanation:

1. x^2 + 2x+ 1

x^2 +1x + 1x + 1

x( x + 1 ) + 1( x + 1 )

( x + 1 ) ( x + 1 )

( x + 1 )^2

2. 9x^2 - 6x + 1

( 3x )^2 - 2 (3x)(1) + (1)^2

(3x - 1)^2

I only know these two..

Hope you are satisfied.
