The discriminant of a quadratic equation is 34. Which of the following is true about its roots? * a. The roots are imaginary and unequal.
b. The roots are real, rational, and unequal.
c. The roots are real, irrational and unequal.
d. The roots are real, rational and equal.

Step-by-step explanation:

The discriminant of a quadratic equation is expressed using the equation:

D = b²-4ac. It talks about the nature of the roots of a quadratic equation.

If D>0, then the roots is real and unequal/distinct

If D<0 the roots are unreal and imaginary

If D = 0, the  roots are real and equal (one real root)

According to this question, since the root given is a real value and also one value, then the the roots are real, rational and equal. Note that the root is rational since we can write it as a ratio of two integers e.g 34 = 34/1. 34 and 1 are integers

the answer

b. they are parallel and will never intersect.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
