  2. Step 2) Find.
  3. Step 3) Find.
  4. Step 4) Add to both sides of the equation.
  5. Step 5) Complete the square on the left-hand-side of the equation.
  6. Step 7) Take the square root of both sides and solve for the variable.

How do you solve completing the square in Class 10?

Step 1: Write the equation in the form, such that c is on the right side. Step 2: If a is not equal to 1, divide the complete equation by a such that the coefficient of x2 will be 1. Step 3: Now add the square of half of the coefficient of term-x, (b/2a)2, on both sides.

How do you solve by completing the square?

Completing the square is a method to solve quadratic equations. To use this method you take the number without a variable and subtract it from both sides, so that it is on the opposite side of the equation. Then add the square of half the coefficient of the x-term to both sides.

What are the steps to complete the square?

Isolate the number or variable c to the right side of the equation.

  • Divide all terms by a (the coefficient of x2,unless x2 has no coefficient).
  • Divide coefficient b by two and then square it.
  • Add this value to both sides of the equation.
  • Rewrite the left side of the equation in the form (x+d)2 where d is the value of (b/2) you found earlier.

    • How to solve an equation by completing the square?

    At first,transform this equation in a way so that this constant term,i.e.

  • Now,if ‘a’ the leading coefficient (coefficient of x2 term) is not equal to 1,then divide both sides via a.
  • After that,add the square of half of the coefficient of ‘x’ (b/2a)2 to both sides of an equation.
