Quadratic Formula and the Discriminant - Algebra I

In this video, you will learn about the quadratic formula and the discriminant. The discriminant is the value that determines how many solutions and the type of solutions that a quadratic equation has. The quadratic formula is a method for solving a quadratic equation. In the quadratic formula, there is a part under the radical, which is b^2-4ac. This part of the formula is what's used to find the value of the discriminant. The first step is to put your quadratic equation into ax^2+bx+c form. Next, you identify the values of a, b, and c. Now you will substitute these values into b^2-4ac to find the discriminant. If the value is positive, there are 2 real solutions. If the value is negative, then there are 2 complex solutions. If the value is equal to 0, then there is one real solution.

Solving Quadratic Equations using Factoring - Algebra I

In this video, you will learn how to solve a quadratic equation using factoring. A quadratic equation is always in the form of ax^2+bx+c. The x^2 term is what makes an equation quadratic. There are several methods to solve a quadratic equation, one of which is called factoring. When factoring to solve a quadratic equation, you first put the equation into ax^2+bx+c form, and then factor to get two binomials. Set each binomial equal to zero, and the numbers you get as a result of solving, will be your solutions to the quadratic equation.

Adding Polynomials - Algebra I

In this video, you will learn how to add polynomial. A  polynomial is a mathematical phrase that includes more than one term. There are two methods to add polynomial. First is to add horizontally and ten second is to add vertically. When you add horizontally, you put a parenthesis around each polynomial and put a plus sign in the middle. Then you simply combine like terms. When you add vertically, you line up the terms on top of each other so that the like terms are lined up. Then you combine the like terms.

Classifying Polynomials - Algebra I

In this video, you will learn how to classify a polynomial. A polynomial can be classified within two categories. The first category is based on the number of terms, and the second is based on the name using the degree of the polynomial. A polynomial is a mathematical phrase that includes more than one term. The degree of a polynomial is the sum of the exponents of the greatest term. Polynomial can be monomials, binomial, or trinomials. A polynomial can also be a constant, linear, cubic, quadratic, or fourth degree.

Standard Form of a Polynomial - Algebra I

The standard form of a polynomial is when you write the polynomial in order of the term with the greatest exponent down to the term with the least exponent. In this video, you will learn how to write the standard form of several polynomials. A polynomial is a mathematical phrase with more than one term. The prefix 'poly' means more than one. To learn more, please watch this algebra video.
