What number should be added to both sides of the equation to complete the square?

lubasha [3.4K]

Answer:

9 should be added to both sides of the equation to complete the square.

Step-by-step explanation:

Given : $x^2 -6x = 5$

To Find: What number should be added to both sides of the equation to complete the square?

Solution:

$x^2 -6x = 5$

Add the square of half of coefficient of x

So, the square of half of coefficient of x = $(\frac{6}{2})^2=3^2 =9$

So, $x^2 -6x +9 = 5+9$

$x^2 -6x +3^2 = 5+9$

$x^2 -2 \times 3 \times x +3^2 = 5+9$

$(x-3)^2 = 5+9$

$(x-3)^2 =14$

Thus 9 should be added to both sides of the equation to complete the square.

The average of four numbers is 26.

Alchen [17]

Answer: 26!!

Step-by-step explanation: the average is like the mean which is all 4 numbers added together divided by 4. 26 times 4 is 104. 20 +42+16 = 78. 104 - 78 is 26 so the 4th number is 26. you can check the work by adding 20 42 16 and 26 together which equals 104. 104 divided by 4 is 26!! so our answer is correct!!
