O level Quadratic and Simultaneous Equations Quiz 1

15 Questions

Quiz Description

 Hello and welcome to this online revision platform, here we have a quiz on quadratic and simultaneous equations with exam standard questions for the ordinary level. Each question has four options and just one of these options is correct. We are now going to briefly talk about what a quadratic equation is and what a simultaneous equation is.

Quadratic equations (also referred to as quadratics) are polynomial equations with degree 2 and this simply means that a quadratic comprises a minimum of one term which is squared. It has as general form, ax² + bx + c = 0 where a is different from zero. A simultaneous equation on the other hand is a set of two or more equations, with each equation containing two or more unknowns.

The Ordinary level gce past questions are all available for you to check them out and see how the exam looks like.
