Identify the number and type of solutions for the equation x^2 − 7x + 3 = 0

1 real
2 real
1 nonreal complex
2 nonreal complex

2 real

Step-by-step explanation:

To answer this question, we need to know whether the discriminant is positive, negative, or zero. The discriminant is the part of the quadratic equation that is under the square root.

Quadratic Equation:  -b±√(b²-4ac)/(2)

The equation is already in Standard Form, so now we need to find the a, b, and c values.

Now we substitute these numbers into the discriminant ( b²-4ac ):

A positive discriminant = two real solutions

A discriminant of zero = one real solution

A negative discriminant = zero real solutions (it would equal nonreal complex solutions instead)
