A quadratic equation can have two real solutions, one real solution, or two complex solutions, none of them real.
Most functions are not like linear equations.
When the equation is in one the following formats: ax2+ bx+c = 0 a(x+b)2+c = 0 (x+a)(x+b) = 0 than it is a quadric. It is also quadratic when x2 and only x2 is in it. example: x2 + 1= 0 and x2=0 are quadratic equations. However ax3+bx2+ cx+d =0 is not a quadratic, this is a cubic because of the x3 term, However you can use the quadric equation to find one of the two answers for it.
x = 4.74 or -2.74
The range is y >= 5.

The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a

One of the most common ways to represent linear equations is to use constants. You can also represent linear equations by drawing a graph.
