To find out the number of real solutions, we use something called "the discriminant". This is usually given the symbol "<span>Δ", pronounced "delta"
</span><span> Δ = b^2 - 4ac, where a is the x^2 coefficient, b is the x coefficient and c is the integer
</span>
When Δ = 0, there is one real solution, when Δ < 0, there are no real solutions, and when Δ > 0, there are 2 real solutions
So, substituting the values in, we get:
Δ = (20)^2 - 4(-4)(-25) = 0
Therefore, there is one real solution to the polynomial given.

We have been given image of circle that passes through point . We are asked to find the radius of the circle.
First of all, we will find the center of the circle.
We can see that center of circle is at point .
Now we will use equation of circle to find radius.
, where, point (h,k) represents center of circle and r represents radius of circle.
Now we will substitute the coordinates of point and coordinates of center and solve for r as:
Switch sides:
Now we will take positive square root on both sides:
Therefore, radius of circle will be and center is at point .
