In this article we cover quadratic equations — definitions, formats, solved problems and sample questions for practice. A quadratic equation is a polynomial whose highest power is the square of a variable x 2 , y 2 etc. For every quadratic equation, there can be one or more than one solution. These are called the roots of the quadratic equation. We have to take two numbers adding which we get 5 and multiplying which we get 6.
They are 2 and 3. Let us verify that. Let us solve some more examples using this method. Till now, the coefficient of x 2 was 1. Let us see how to solve the equations where the coefficient of x 2 is greater than 1. Here, the coefficient of x 2 is 3. In these cases, we multiply the constant c with the coefficient of x 2. The factoring method is an easy way of finding the roots.
But this method can be applied only to equations that can be factored. Hence this quadratic equation cannot be factored. When we get a non-perfect square in a square root, we usually try to express it as a product of two numbers in which one is a perfect square. This is for simplification purpose. Here 28 can be expressed as a product of 4 and 7. So this can be solved by the factoring method.

Use 2cm to represent 1 unit on the x-axis and 1cm to represent 5 units on the y-axis. Thanks you God bless you!!! Your email address will not be published. Tags gmat quantitative. Definitions A monomial is an algebraic expression with only one term in it. Example: x 3 , 2x, y 2 , 3xyz etc. A polynomial is an algebraic expression with more than one term in it.
A polynomial that contains two terms is called a binomial expression. A polynomial that contains three terms is called a trinomial expression. A quadratic equation may be expressed as a product of two binomials. Let us express the middle term as an addition of 2x and 3x. The roots of this equation -2 and -3 when added give -5 and when multiplied give 6.
Solved examples of Quadratic equations Let us solve some more examples using this method. This can be done by expressing 18x as the sum of 11x and 7x. For this kind of equations, we apply the quadratic formula to find the roots.
Let us consider another example. So it has complex roots. Let us verify this. Hence verified. Quadratic Equations Quiz: Solve the following Problem 1. All of the above. Answer 1.
