There are two distinct solutions x to the equation 18 + 5x^2 = 30x. If each solution is rounded to the nearest integer, and then these two integers are multiplied together, what is the result?

Hello Guest!

 

\(5x^2-30x+18=0\\ x^2-6x+3.6=0\\ x=3\pm \sqrt{9-3.6} \)

\(x\in \{0.67621,\ 5.32379\}\)

\(1\times 5=5\)

The result is 5.
