Quadratic equation question is one of the most common questions to expect in O-Level, JAMB and Post-UTME.
In this article we would be looking at Simple Math but Can you Solve it? Quadratic Challenge.
So, if you know how to solve quadratic, it is like saying you’ve already answered at least one math question in the exams mentioned above.
A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2. There are three main ways to solve quadratic equations: 1) to factor the quadratic equation if you can do so, 2) to use the quadratic formula, or 3) to complete the square. If you want to know how to master these three methods, just follow these steps.
- 1Set up your expression. The standard format for the quadratic equation is:
ax2 + bx + c = 0
Start by ordering the terms in your equation from highest to lowest power, just like this standard format. For example, take:
6 + 6x2 + 13x = 0
We will re-order this expression so it’s easier to work with by simply moving the terms around:
6x2 + 13x + 6 = 0
- Find the factored form using one of the methods below. Factoring the polynomial will result in two smaller expressions which can be multiplied to produce the original polynomial:
