This math video tutorial gives a step by step explanation to a math problem on "Completing The Square 5".

Completing the square 5 video involves completing the square, equations, quadratic equations, solving equations, solving quadratic equations. The video tutorial is recommended for 5th Grade, 6th Grade, 7th Grade, 8th Grade, 9th Grade, 10th Grade, 11th Grade, and/or 12th Grade Math students studying Algebra, Calculus, Pre-Algebra, Pre-Calculus, and/or Advanced Algebra.

An equation is a mathematical statement, in symbols, that two things are the same (or equivalent). Equations are written with an equal sign. Equations are often used to state the equality of two expressions containing one or more variables.

In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is

*a*x^{2} + *b*x + *c* = 0

where a ≠ 0. (For a = 0, the equation becomes a linear equation.)

The letters*a*, *b*, and *c* are called coefficients: the quadratic coefficient *a* is the coefficient of x^{2}, the linear coefficient *b* is the coefficient of x, and *c* is the constant coefficient, also called the free term or constant term.

Quadratic equations are called quadratic because quadratus is Latin for "square"; in the leading term the variable is squared.

where a ≠ 0. (For a = 0, the equation becomes a linear equation.)

Quadratic equations are called quadratic because quadratus is Latin for "square"; in the leading term the variable is squared.

Solving an equation means finding a value for the variable that makes the equation true.
