The Quadratic Eq;n , when plotted on gaph paper, will reveal a parabola.
This patrabola can intersect the x-axis in two places, just touch the x-axis or miss it altogether.
The roots of a quadratic eq;n are the point(s) were the parabola intersects the x-axis.
If is intersects at two points, then there are two roots. If it just touches the x-axis, then there is one root only. If it does not touch the x-axis, then the eq'n remains unresolved.

What is the solution to the quadratic equation x2 plus 10x plus 25 equals 7?
Using the quadratic equation formula: x = -5-/+ the square root of 7
What are the roots of the quadratic equation below?
That depends on the equation.
How do you know if a equation is a quadratic one?
You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.
What would be the most logical first step to solve this quadratic equation?
take the square root of both sides.
What is an equation that can be used in quadratic formula completing the square and factoring?
A quadratic equation.
