Question

Which equation can be solved using using the expression below for x?

Answer 1

0 = 10x^2 + 3x + 2

Explanation:

That is the quadratic formula:

x = -b +- sqrt( b^2 - 4ac) / 2a

It is used for an equation in the form 0 = ax^2 + bx + c

so just plug a, b, and c, from the quadratic formula into that equation
