What is the radicand (the number inside the radical) of the solution to f(x)=-2x2+x+5?

Answer 1

The radicand of a solution to a quadratic equation is the discriminant.

In the quadratic equation f(x) = -2x^2 + x + 5, the discriminant is found by using the formula:

D = b^2 - 4ac

Where a = -2, b = 1, and c = 5.

Therefore, the discriminant is:

D = (1)^2 - 4(-2)(5)
D = 1 + 40
D = 41

So, the radicand of the solution to the quadratic equation f(x) = -2x^2 + x + 5 is 41.
