Easy -1.8 This is a straightforward algebraic expansion and simplification requiring only basic manipulation of brackets and collecting like terms. It's purely procedural with no problem-solving element, making it significantly easier than average A-level questions which typically require multiple techniques or conceptual understanding.
1 Express \(2 x ( x + 3 ) + 5 x ^ { 2 } - 2 ( x - 3 )\) in the form \(a x ^ { 2 } + b x + c\), where \(a , b\) and \(c\) are integers to be determined.
1 Express $2 x ( x + 3 ) + 5 x ^ { 2 } - 2 ( x - 3 )$ in the form $a x ^ { 2 } + b x + c$, where $a , b$ and $c$ are integers to be determined.
