FP2.1.1 - Manipulation and solution

The manipulation and solution of The solution of inequalities such as algebraic inequalities and 1 x inequations, including those >, | x2 − 1 | > 2(x + 1). x − a x − b involving the modulus sign.

Use fp2.1.1 - manipulation and solution to connect the rule to the data and decision in the question.

This matters because fp2.1.1 - manipulation and solution determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp2.1.1 - manipulation and solution to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: FP2.1.1 - Manipulation and solution is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
