​

Answer 1

Explanation:

where is the image?...

Answer 2

Answer:

wo zero's of equation of 2x

4

−3x

3

−3x

2

+6x−2 are

,−

2

then (x+

2

)(x−

2

) is factor of equation given hence

ref. image

⇒(x

−3x+1)=(2x

4

−3x

3

−3x

2

+6x−2)

2x

2

−3x+1=0

⇒2x

2

−2x−x+1=0

2x(x−1)−1(x−1)=0

x=
