Because all positive numbers have 2 square roots, eg 9 = 3 x 3 and also -3 x -3

How many solutions can a quadratic-linear system have?

A quadratic-linear system can have either zero, one, or two solutions, depending on the specific equations involved. If the quadratic and linear equations intersect at two points, there are two solutions; if they touch at one point (the vertex of the quadratic lies on the line), there is one solution; and if they do not intersect at all, there are zero solutions. The nature of the solutions is determined by the relative positions of the parabola and the line in the coordinate plane.


What is the difference of linear equations from quadratic equations?

Linear equations are polynomial equations of the first degree, meaning they have the highest exponent of one, and they graph as straight lines. In contrast, quadratic equations are polynomial equations of the second degree, characterized by the highest exponent of two, and they graph as parabolas. This fundamental difference in degree affects their solutions and the nature of their graphs. Additionally, linear equations have a single solution, while quadratic equations can have zero, one, or two solutions.


Is it possible for a quadratic equation to have more than 2 solutions?

No because quadratic equations only have 2 X-Intercepts
