1. For y = (x + 2)(x − 5), state the x-intercepts.
Hint
Each bracket gives one root.
Higher Mathematics
Cross-topic Higher Mathematics revision routes for algebraic fluency, functions, calculus, trig, vectors and exam-style reasoning.
Choose a mode, answer the generated set, then use the feedback to target the weakest Higher topic families.
Each bracket gives one root.
Find the radius gradient first, then use the negative reciprocal.
Find the composite first, then use the word hence to solve the resulting quadratic equation.
Use 180° = πradians.
Positive derivative means increasing; negative derivative means decreasing.
The line is above the axis, so the integral gives the area.
Revision mode
Try a short mixed set to warm up key Higher Mathematics skills.
Revision mode
Work through a broader mixed set across the main course areas.
Revision mode
Practise linking functions, graphs, differentiation and integration.
Revision mode
Choose methods, combine topics and explain your reasoning.
