Question

7. The degree of the equation x2 – 2x + 1 = x2 – 3 is (b) 2 (C) 3 (d) 0 O (a) O (b) (c) O (d) 22​

Answer 1

Answer:

Given: quadratic equation x2−2x+1=0

To find the value of x+x1

x2−2x+1=0 

⇒x2+1=2x 

⇒xx2+1=2

 

⇒x+x1=2

Answer 2

$\bold {x {}^{2} - 2x + 1 = x {}^{2} - 3} \\ \\ \bold{{x}^{2} - x {}^{2} - 2x + 1 + 3 = 0} \\ \\ \bold{ - 2x + 4 = 0} \\ \\ \bold \blue{So \: degree \: of \: polynomial \: is \: 1.}$
