Answer 2

The equation that can be solved using the expression is:

B.
`10x^2+3x=2`

Explanation:

We know that for any quadratic equation of the type:

`ax^2+bx+c=0`

The solution for 'x' is given by the formula:

`x=(-b\pm √(b^2-4* a* c))/(2a)`

Hence, by comparing the given expression with the formula we see that:

b=3, a=10 and c= -2

Hence, we have the quadratic equation as:

`10x^2+3x-2=0`

or it can also be represented as:

`10x^2+3x=2`

Hence, option: B is the correct answer.
