Solve a quadratic to two decimal places, a quadratic inequality, a factorised equation and a surd equation. Solve a linear and a quadratic equation simultaneously, then find the smallest integral value of a parameter for which the roots of a given quadratic are non-real. The second question simplifies powers in prime bases without a calculator, solves an equation reducible to a quadratic, and solves a second pair simultaneously.
