Year 11 Algebra Worksheets (GCSE) | Printable PDFs
Year 11 Algebra worksheets for Year 11 Maths (Key Stage 4, GCSE). Students aged 15-16 learn how to solve equations by Completing the Square. For other methods to solve Quadratic Equations, namely Factorising Quadratic Euqtaions and the Quadratic Formula try Year 10 Algebra Worksheets.
Year 11 students also learn how to identify, continue and find rules for quadratic sequences.
A quadratic sequence is a sequence where the second differences are constant. For example; 1, 4, 9, 16, 25. Students also learn how to evaluate functions, inverse functions and composition functions.

Common Questions about Year 11 Algebra
What is an inverse function?
An inverse function reverses the effect of the original function, taking outputs back to their original inputs.How do you find the inverse of a function?
Replace f(x) with y, swap x and y, then rearrange the equation to make y the subject.What is a composite function?
A composite function is formed when one function is applied after another, such as f(g(x)), where the output of one function becomes the input of the next.
Year 11 Algebra Common Mistakes
Common Mistake 1
Students sometimes forget to swap x and y when finding an inverse function. This means they only rearrange the original function rather than finding the inverse.Common Mistake 2
Students often mix up the order in composite functions. For example, f(g(x)) means apply g first, then apply f to the result.Common Mistake 3
Students may forget to simplify carefully after substituting one function into another, especially when brackets, negatives or fractions are involved.
