O level Quadratic and simultaneous Equations Quizzes
A quadratic equation is any equation of the form ax² + bx + c = 0 Where x is a variable, a, b and c being real numbers (R), where a≠0 because if a=0 then the equation becomes a linear equation and not a quadratic equation. The values of x that satisfy the a quadratic equation are always refered to as the solutions of the equations and a quadratic equation has a maximum of two solutions. Also, given ax² + bx + c The values of x that will satisfy the above expression are known as zeros or roots of the quadratic expression. A simultaneous equation is a set or system of equations, usually linear equations involving at least two unknowns (variables) in the form ax + by = c dx + ey = f Where a,b,c,d,e and f are real numbers (R) while x and y are the variable. There are two method of solving simultaneous equations; the elimination and the substitution method.

Quadratic Equation
A quadratic equation is any equation of the form
ax² + bx + c = 0
Where x is a variable, a, b and c being real numbers (R), where a≠0 because if a=0 then the equation becomes a linear equation and not a quadratic equation.
The values of x that satisfy the a quadratic equation are always refered to as the solutions of the equations and a quadratic equation has a maximum of two solutions.
Also, given
ax² + bx + c
The values of x that will satisfy the above expression are known as zeros or roots of the quadratic expression.
Methods of Solving quadratic equations
There are basically two ways of solving quadratic equations and there are so many quizzes here at gcequiz.com that will test your ability to solve quadratic equations.
1. The factorization method
This involves finding the factors of ac that will sum up to give b then factorizing the quadratic equation.
2. Completing the squares
In this method,
* Make the coefficient of x² unity by dividing all through by a
* Move the term independent of x to the right hand side of the equation
* Take half of the coefficient of , square it and add to both sides
* Simplify the right hand side and bring the left hand side together
* Now make x the subject of the formula by taking the square root of both sides and moving the constant term to the right hand side of the equation and simplifying the right hand side.

Simultaneous Equations
A simultaneous equation is a set or system of equations, usually linear equations involving at least two unknowns (variables) in the form
ax + by = c
dx + ey = f
Where a,b,c,d,e and f are real numbers (R) while x and y are the variable.
