Easy -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.
## 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
