Question

Can any one pls tell me how to do the method of completing the square.

Answer 1

Answer:

Step 1 Divide all terms by a (the coefficient of x^2).

Step 2 Move the number term (c/a) to the right side of the equation.

Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

We now have something that looks like (x + p)2 = q, which can be solved rather easily:

Step 4 Take the square root on both sides of the equation.

Step 5 Subtract the number that remains on the left side of the equation to find x.

Answer 2

.Ensure that coefficient of x^2 is 1, if it is not so then divide the equation by that no.

.find third term by using formula

(1/2 * coefficient of x)^2

.add third term on both sides

.take compact form

.find square roots
