Incredible How To Solve Quadratic Functions By Completing The Square References

We Now Have Something That Looks Like (X + P) 2 = Q, Which Can Be Solved Rather Easily:

If the coefficient of x 2 is 1 (a = 1), the above process is not required. Quick and simple method by premath.com Here, we shall discuss a method known as completing the square to solve such quadratic equations.

Separate The Variable Terms From The Constant Term.

Completing the square involves creating a perfect square trinomial from the quadratic equation, and then solving that trinomial by taking its square root. It contains plenty of examples and practice problems. In the given quadratic equation ax 2 + bx + c = 0, divide the complete equation by a (coefficient of x 2 ).

Then, We Can Use The Following Procedures To Solve A Quadratic Equation By Completing The Square.

We will use the example [latex]{x}^{2}+4x+1=0[/latex] to illustrate each step. Add (b/2)^2 to both sides. Set one side of the equation equal to zero.

Solve The Given Quadratic Equation X 2 + 8 X + 4 = 0.
