We create empirical formulas by dividing the number of atoms in a molecular formula by their greatest common denominator, the largest possible number that is a factor for all the numbers in the formula. This shows us the ratio of the atoms but it is not considered a true formula because it...

subtraction and division are easy. However, to solve algebraicexpressions, and other complex operations we use mathematical formulas. These are quite useful in obtaining the answers precisely. Cuemath provides formulas for each math topic along with the illustrated steps of equations for students to un...
Factorizing formulas in algebra is especially important when solving quadratic equations. Also, while reducing formulas we normally have to remove all the brackets. In particular cases, for example with fractional formulas, sometimes we can use factorization to shorten a formula. The term is something...
~b,~c \in \mathbb{C}$) are quadratic equations, where, a, b, c are coefficient of $x^2, x$ and the constant term. As it has power 2, it will have two roots. In this part, we will calculate roots by various methods and try to generalize formulas that will be useful in JEE...
