The quadratic equation has no real roots. This means the line and point has no point of intersection.
<h3>System of equations</h3>
System of equations are equations that is more than one and have two or more unknowns.
Given the simultaneous equation
x^2 + y^2 = 25
2x + y = 25
from equation 2;
y = 25 - 2x ................3
Substitute equation 3 into 1 to have:
x^2 + (25-2x)^2 = 25
x^2 + 625 - 100x + 4x^2 = 25
5x^2 -100x + 600 = 0
x^2 -20x + 120= 0
Hence the quadratic equation has no real roots. This means the line and point has no point of intersection,
