Question

Anyone plz tell me how to do completing square​

Answer 1

Answer:

Step 1

First make the coefficient of x² 1 by dividing. For eg if you have suppose 2x² then divide the equation by 2

Step 2

Add and subtract half of the coefficient of x to the square with the equation.

For eg you have this equation

x²+3x+2

coefficient of x= 3 3

half of coefficient of x = 3/2

(half of coeffiect)2 = 9/4

Add and subtract the number so the equation doesn't change

x²+3x+9/4 +2 -9/4

Combine the terms and you get full marks. Easy
