### Stepwise Tips to practice a Quadratic Equation:

• Firstly the candidate needs to note down twenty sums related to the quadratic equation on a page.
• Then ten sums are to be solved using basic formula.
• To solve these sums using a stopwatch will help in time management.
• The next step is to evaluate the time taken and analyse the performance.
• The remaining ten questions are to be solved next by applying the shortcut tricks.
• The time taken should be noted carefully.
• This will surely have a difference from the time taken while solving the first ten questions.
• Practice is the key to master this topic of the Quantitative Aptitude section.

The basic equation of quadratic equation is $ax^{2}+ bx+c =0$ where this equation is equal to zero and a,b,c are constants. The quadratic equation only holds the power of x where x is also known as a non-negative integer.

For example: $6x^{2} + 11x +3= 0$

Solution: In this equation 6 is the coefficient of $x^{2}$

11 is the coefficient of x and 3 is constant. The easiest way is to solve this through the middle term break method.

First step:  To multiply $(+6)\times (+3)$ = +18

Second step: +18 is to be broken into two parts in such a way that their addition results in the middle term that is 11 where $9 + 2 = 11$ and product of these factors are 18.

Third step: To change the sign of the factors where +9 = -9 and +2 =-2 and this has to be divided by coefficient of $x^{2}$. Therefore, $-9/6 = -3/2$ and $-2/6 = -1/3$.

### Top 3 Tips to solve Quadratic Equations in Bank Exams

The major three ways to solve the problems on the Quadratic Equation are as follows:

1. To factor the Quadratic Equation- Here all the same terms are to be combined and to the one side of the equation in such a way that there remains nothing on the other side. Once it has no remaining terms we can write zero.
For example: $3x^{2} – 8x -4 = 3x + x^{2}$ $4x^{2} – 11x – 4=0$ The second step is to factor the equation so that there is a set each through the middle term break method. The last part is to separate each factor set to zero.
For example: $(3x+1)(x-4)=0$
2. To use the formula- The sums can be solved through the formula $\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$ and solve putting the equations in this.
3. To complete the square- This process is bit complex while the other two are easy to solve.
