Question

Factorise the Polynomial:-
x^2-2+1/x^2-y^2
And Show working also.

Answer 1

Your answer is given below =》》》

x²+1/x² +2 -2x-2/x

=(x+1/x)² - 2(x+1/x)

=(x+1/x)(x+1/x -2)

Answer 2

Step-by-step explanation:

STEPS OF CONSTRUCTION:

1.Draw line segment of length AB=8cm.

2. Draw any Ray AX making acute ∠BAX with AB

3. Draw a parallel to BY parallel to AX by making∠ABY=∠BAX.

4. Make 3 points A
