Important Quadratic Questions PDF for SBI PO Pre 2023 , NRA CET , RRB Scale 1 Pre at Smartkeeda

   
We have to solve both of the Quadratic equations to get to know the relation between both the variables.
 
Suppose we have two variables ‘x’ and ‘y’. The relationship between the variables can be any one of the following:
 
x > y
x < y
x = y or relation can’t be established between x & y
x ≥ y
x ≤ y
 
Meaning of different symbols, Before getting deep into the quadratic equations, lets try to understand the meaning of the basic operations used in finding the relationship between the variables –
 
(1) ‘>’ symbol: This symbol indicates that variable on the left side is definitely greater than the variable on the right side of the symbol.
 
For example:  x > y means x is definitely greater than y.
(2) ‘<’ symbol: This symbol indicates that variable on the left is definitely smaller than the variable on the right side of the symbol.
For example: x<y means x is definitely smaller than y.
 
(3) ‘=’ symbol: This symbol indicates that variable on the left side is equal to the variable on the right side of the symbol.
For example: x = y means x is definitely equal to y.
 
(4) ‘≥’ symbol: This symbol indicates that variable on the left side is either greater than or equal to the variable on the right side of the symbol.
For example:  x ≥ y means x is either greater than y or equal to y.
(5) ‘≤’ symbol: This symbol indicates that variable on the left side is either smaller than or equal to the variable on the right side of the symbol.
 
For example: x≤y means x is either smaller than y or equal to y.
 
General form of a Quadratic Equation
ax² + bx + c = 0
 
Quadratic equation means that it will definitely have the maximum power of the variable as ‘2’ which means we will always see ax² term in a quadratic equation.
 
Or we can say that b can be 0, c can be 0 but a will never be 0.
 
While solving quadratic equation, you will always get 2 values of the equation. These 2 values are called roots of the equation. The roots of the equation always satisfy the equation. So in case of doubt, we can check the solution by putting the values back into the equation. If the equation turns out to be zero then our roots are correct.
 
Here are different kind of example of Quadratic Equation , so that we will get a very clear concept of the basic formation of a quadratic equation to get prepared for SBI PO Pre 2023.
