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?
The result is -35.
18 + 5x^2 = 30x.
5x^2 - 30x + 18 =0
Use the quadratic formula to get:
x= 5.323790008 x= 0.6762099923
5.323790008 * 0.6762099923 = 3.6
