Answer:
To make the equation complete square , we have to add 11 .
Step-by-step explanation:
Given as :
The linear equation is
x² + 4 x - 5 = 2
Now, move the constant to left side of equation
So, x² + 4 x - 5 - 2 = 0
Or, x² + 4 x - 7 = 0
<u>Now, to make equation complete square , let add 11 both side</u>
So, x² + 4 x - 7 + 11 = 11
Or, x² + 4 x + 4 = 11
Now, applying mid-term break
So, x² + 2 x + 2 x + 4 = 11
Or, x ( x + 2) + 2 (x + 2) = 11
Or, (x + 2) ( x + 2) = 11
Or, (x + 2)² = 11
Hence, To make the equation complete square , we have to add 11 . Answer
