Question

6. Factorise each of the following: 1 (i) 3x4 – 7x2y2 + 2y4 (ii) x2 + - 3 x2​

Answer 1

this is the answer for 1st one

Given x 2

−3x+2=0

x 2−2x−1x+2=0 (Resolving the expression)

x(x−2)−1(x−2)=0 (Taking common factors)

(x−2)(x−1)=0 (Taking common factors)

∴x−2=0 or x−1=0 (Equating each factor to zero)

∴x=2 or x=1

∴2 and 1 are the roots of x 2

−3x+2=0

this is the answer for 2nd one

hope this answer helps you
