A quadratic equation is an equation that has at least one term squared. It is an equation of second degree. ax^2 + bx + c = 0 is a typical quadratic equation. a, b and c are numerical constants called coefficients.

Completing the square method is one of the four ways of solving quadratic equations. The three others are Graphing, Quadratic Formula or Formula Method and Factoring.

You must know how to make an expression a perfect square to be able to solve quadratic equations using completing the square method.

A transversal is a line that cuts or passes through two or more lines in the same plane at two distinct points.
Transversals help establish whether two other lines in the Euclidean plane are parallel.
It is called a perpendicular transversal if it crosses the parallel lines at right angles.
