Please help!!!

Answer 1

Answer:

The equation that can be solved using the expression is:

        B.   $10x^2+3x=2$

Step-by-step 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:

$x=\dfrac{-b\pm \sqrt{b^2-4\times a\times c}}{2a}$

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.
