Given:
The equation is:
To find:
The number that should be added to sides of the equation to complete the square.
Solution:
If an expression is in the form of , then we have to add to make it perfect square.
We have,
...(i)
To make it perfect square we need to add square of half of coefficient of x on both sides.
Coefficient of x is -10, so square of half of coefficient of x is:
On adding 25 on both sides of (i), we get
Therefore, we need to add 25 to both sides of the equation to complete the square.
The answer is 0.3.
Take for instance, a numberline. The positive numbers are always greater than the negative numbers. Even though you have this type of question:
Which number is greater +100,000 or -100,000?
The answer would still be 100,000 because any positive number is always greater
