Friends today we are going to discuss that “ how can we solve algebra Problems with ease?”. As we know that there are various types of algebra equations which may be of linear or non- linear form and categorized in three major parts of algebra Elementary algebra, Linear algebra and Abstract algebra. Elementary algebra is the basic and initial level algebra in which algebra problems are in simple expression form with arithmetic operators and numerical values or variables, whereas Abstract algebra have some real and complex numbers involvement to form algebraic equation and Linear algebra includes all the standard algebraic equation of linear form in it.
Let us take an example of quadratic equation which is also an algebraic equation and see “ how to solve quadratic equations ”. Quadratic equation is the algebraic equation of second order and its standard form is as:
cy2 + dy + f = 0
here c,d, and f are integer coefficients and y is a variable. Because of 2nd order, Quadratic equation solution gives two roots of the unknown variable in the equation and these roots may or may not be of real form. These roots are calculated by using standard quadratic formula which is as:
for first root = (-d + ( √(d2 – 4 cf) )) / 2 c
second root = (-d - √( d2 – 4 cf) )) / 2 c
in this formula a sub part (d2 – 4 cf), is known as Discriminant and it is represented as “∆”.
according to the value of discriminant the behavior of the roots is decided,
To solve quadratic equation in a quick while students can use the online calculator which is Quadratic formula solver. If the value of ∆ is a non- zero integer than roots are distinct and when discriminant is positive too then roots are distinct but real.
