Quadratic simultaneous equations worksheet

A sequence of lessons I have now successfully delivered to a Year 9 and Year 10 top set and a Year 10 set 2. The students were confident in carrying out the skill of solving quadratic simultaneous equations.

Supercharge your learning. Simultaneous equations are multiple equations that share the same variables and which are all true at the same time. When an equation has 2 variables its much harder to solve, however, if you have 2 equations both with 2 variables, like. These equations are called simultaneous for this reason. There are 2 main types of equation you need to be able to solve. We will write one equation on top of the other and draw a line underneath, as with normal subtraction.

We will also discuss their relationship to graphs and how they can be solved graphically. Quadratic simultaneous equations are two or more equations that share variables that are raised to powers up to 2 e. Below are examples of quadratic simultaneous equations that are made up of a pair of equations; one linear equation and one equation with quadratic elements. One key difference of quadratic simultaneous equations is that we can expect multiple answers. This is because of the way the graphs of linear and quadratic or other non-linear functions can intersect. On the graph below we can see the straight line of the linear equation has crossed the curved parabola of the quadratic equation at two points of intersection. Includes reasoning and applied questions. Quadratic simultaneous equations is part of our series of lessons to support revision on simultaneous equations. You may find it helpful to start with the main simultaneous equations lesson for a summary of what to expect, or use the step by step guides below for further detail on individual topics. Other lessons in this series include:. See below for example solutions to three common forms of simultaneous equations involving quadratic. Another way to think about this is that as both equations are equal to y , they must therefore be equal to one another. NOTE: here we have solved by factorising but you could also solve by using the quadratic equation or by completing the square. NOTE: we have found two possible values of x by using the quadratic equation.

Example: Find the solution to the following simultaneous equations. The coefficients are the numbers before x and y , make the x coefficients the same by scaling up both equations. Step 3: Add or subtract the equations to eliminate terms with equal coefficients.
