TopicPartial Fractions
TypeSimplify algebraic fractions by addition or subtraction
DifficultyEasy -1.8 This is a straightforward algebraic manipulation requiring only finding a common denominator and combining two fractions—a basic skill tested early in A-level. It involves no problem-solving, just routine application of fraction addition with linear denominators.
Spec1.02k Simplify rational expressions: factorising, cancelling, algebraic division

1 Express \(\frac { 2 } { x - 1 } + \frac { 5 } { 2 x + 1 }\) as a single fraction.

Question 1:
AnswerMarks Guidance
\(\frac{2(2x+1)+5(x-1)}{(x-1)(2x+1)}\)M1 AO 1.1
\(= \frac{9x-3}{(x-1)(2x+1)}\)A1 AO 1.1
[2 marks]
## Question 1:

$\frac{2(2x+1)+5(x-1)}{(x-1)(2x+1)}$ | M1 | AO 1.1 |

$= \frac{9x-3}{(x-1)(2x+1)}$ | A1 | AO 1.1 | Numerator should be simplified but need not be factorised, and denominator may be expanded, but mark final answer
