Help your students prepare for their Maths GCSE with this free quadratic simultaneous equations worksheet of 34 questions and answers
Quadratic simultaneous equations are pairs of equations where one is one quadratic and one linear.
To solve quadratic simultaneous equations we can use the elimination method in a similar way to solving linear simultaneous equations. We need to substitute the linear equation into the quadratic (non-linear) equation which may have one variable which is squared, or both variables which are squared. This quadratic equation is then solved and two solutions are found. Both of these solutions need to be substituted one at a time into the first equation or the second equation to calculate two pairs of solutions.
In order to answer these questions, a strong understanding of solving quadratic equations by factorising or using the quadratic formula is required. The final answers can be given as integers, fractions, decimals or surds as required.
Quadratic simultaneous equations can be used to find where a line intersects a parabola or a circle. This can be extended to calculating the equation of a tangent to circle.
There will be students in your class who require individual attention to help them succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
Help your students feel confident with exam-style questions and the strategies they’ll need to answer them correctly with our dedicated GCSE maths revision programme.
Lessons are selected to provide support where each student needs it most, and specially-trained GCSE maths tutors adapt the pitch and pace of each lesson. This ensures a personalised revision programme that raises grades and boosts confidence.
