The usual methods of solving quadratic equations apply to this one. Any of them can be used: graphing, factoring, completing the square, quadratic formula.
<h3>Solution</h3>
Often, when the coefficients are non-integers and have no obvious relationship to each other, the most convenient method of solution is the quadratic formula. It tells you the solution to ax²+bx+c=0 is ...
Your equation has the coefficients, a = -0.07, b = 0.007, c = 5, so the solutions are ...
