Solve the following quadratic equation by factorization method

3

2 − − 10 = 0​

Answer 1

Answer:

3

2x

−3×10×3

x

+81=0

⟹3

2x

−3

x+1

×10+3

4

=0

⟹(3

2

−30×(3

x

)+81=0

Let, 3

x

=u

⟹u

2

−30u+81=0

⟹u

2

−27u−3u+81=0

⟹u(u−27)−3(u−27)=0

⟹(u−3)(u−27)=0

When, u=3

⟹x=1

And when, u=27

⟹x=3
