Question

14. Solve by completing square method.
9x²-3x-2=0​

Answer 1

Answer:

first,we have to take coefficient of x^2 common

after taking 9 common equation will be like this

9(x^2-3x/9-2/9)=0

9 will go right side

x^2-3x/9-2/9=0/9

0/9 means 0

x^2-3x/9-2/9=0

x^2-3x/9=2/9

after solving we get

9x^2-3x/9=2/9

do the cross multiplication

we get

9x^2-3x-2=0

do the factorization

after factorization we get

(3x+1) (3x-2)

means there is two value of x

1.x=-1/3

2.x=2/3
