Any object occupies space, area. If an object is triangular, it will occupy a triangular space on the surface it rests. This tutorial will uncover four different ways of calculating area of triangles. That will depend on the measurements that you have.

A curve that is symmetrical with regards to a line of symmetry and its focal point lies on that line is a parabola. To make the definition very clear, we need to understand each technical term in it. Focus – This is a fixed point on a line of symmetry where any reflection from the parabola curve converges. Directrix – This is a straight line on the opposite side of the parabolic curve, a certain distance from the vertex.

This tutorial assumes that you are through with lessons on factoring quadratic equations and solving quadratic equations. A quadratic inequality is just like a quadratic equation where the inequality sign replaces the equal sign. As such, the solution of quadratic inequalities follows the same method for solving any quadratic equation

Algebraic fractions are easy to simplify just like fractions involving real numbers. The simplification process is even shorter when the complex fractions have a common denominator. In such a case, we only need to remove the denominator by multiplying both top and bottom by it. The remaining step is just simplification.

If a polynomial has only three terms, then we call it a trinomial. In this course, we are going to discuss trinomials with an exponent of 2. In other words, we will only look at quadratic trinomials.
