Answer:

Now we can solve a Quadratic Equation in 5 steps:

Step 1 Divide all terms by a (the coefficient of x2).

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.

Answer:

Example:

  • x^2+4x+3=0
  • x^2+4x+4-1=0            here we add 1 to 3 and remove 1 to complete a square of (x+2)
  • (x+2)^2 - 1=0              here we have square and 1 can be shown as 1^2
  • using a^2-b^2=         (a+b)(a-b) formula to factorize the polynomial
  • (x+2)^2- 1^2=0
  • (x+2+1)(x+2-1)=0
  • (x+3)(x+1)=0
  • x+3=0 and x+1=0

now easily solved
