Friends, today we all are going to learn about the concepts behind Radicals and various factoring techniques in mathematics. Some students shy in asking their problems to their school teachers, as believe that what other students will think about me. This shyness might decrease the interest of students in maths and may harm them in their studies. This problem can be sort by using Online math tutor .



Now I am going to discuss about Radicals. Radical is known as root of an expression. A fraction is not a radical, but a fraction may contain a radical. It uses the the sign of radical (√) also known as surds. To understand it better let's take an example:

22 = 4 it means 2 is the square root of four. 2³ = 8 this means 2 is the cube root of 8. if a, b are real numbers, n is a positive integer and if an = b then the n th root of b is a. then it can be written in this form : n root b = a

In n root b, n is the indexed and b is the radicand. The index give the degree of the roots.



Simplifying Radicals is not an easy task, if the expression comes with decimal values or expression with a large number then it is quite difficult to find the root of the same value. The steps to solve radical problems are break or isolate the radicals to the left side of equal sign means get one radical on one side and everything else on the other using inverse operations. . Then square each side of the equation and by solving the equation we get all the solution.



Let's discuss about factors in mathematics. A factor, in maths terms means a number that divides into a given number with no remainders. Before factoring a third order or degree polynomials or factoring trinomials we need to understand the basic concept behind the polynomials having order three. A polynomial contains a variable (x) raised to a power, known as a degree, and several terms and/or constants. To factor a polynomial means to break the expression down into more manageable chunks that are multiplied together. The standard form of a quadratic equation: ax3+ bx2+ cx = 0



Online factoring calculators are also available which will attempt to factor the expression by dividing it with a GCF, and identifying a difference between two squares, or factorable trinomials.
