Question

12. Find HCF of (x^ 3 -3x+2 ) d(x ^ 2 - 4x + 3)​

Answer 1

Answer:

Correct option is A = (2X−3)

Step-by-step explanation:

x4−x2−6 can be factorized as

=x4−3x2+2x2−6

=x2(x2−3)+2(x2−3)

=(x2−3)(x2+2)

and x4−4x2+3 can be factorized as

=x4−3x2−x2+3

=x2(x2−3)−1(x2−3)

=(x2−3)(x2−1)

Therefore, H.C.F is (x2−3)
