Determine the nature of the roots: 5x^2+20x+20=0
a.
no real solutions
c.
cannot be determined
b.
a unique real solution
d.
two distinct real solutions

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
