The quadratic equation is resolved in mathematics using the completing the square approach. In this approach, we modify the given equation’s form so that the left side should be a perfect square binomial. This approach requires that the equation take the form \( ax^2+ bx+ c=0 \). Completing the square method helps solve quadratic equations that can’t be solved using quadratic formulas.
A quadratic equation’s root or solution is essentially a number that satisfies the equation. The value on the right side of the equation will be equal to the value on the left side if we substitute the number on the left side.
Any quadratic equation can be solved using one of three methods:
The factoring approach is one of the fundamental methods for solving a quadratic equation. However, this approach is only helpful for a particular class of quadratic equations. On the other hand, we can use the quadratic formula and complete the square procedures to resolve almost all varieties of quadratic problems. Moreover, the completing square technique is helpful because not all such equations can be factored in.
What is Completing the Square?
Writing a quadratic expression containing the perfect square is known as “completing the square” in algebra. In other words, the act of “completing the square” can be described as taking the quadratic equation “\(ax^2 + bx + c = 0\)” and changing it to “\(a(x + p)^2 + q = 0\).” This approach is used to find the quadratic equation’s roots.
