Using the Quadratic Formula
What is the resource?
This PDF delves into the quadratic formula, that equation with 'x equals'. It explains how to use it to solve tricky equations and is best for older secondary students.
Why is the quadratic formula important?
Quadratic equations appear in loads of unexpected places:
- Engineering: The paths of thrown objects (like rockets) are modelled by quadratics.
- Physics: Motion problems, energy formulas – many involve these equations.
- Even business: Quadratics can help find break-even points or maximum profits.
Why is this resource helpful?
The quadratic formula is a powerful weapon in maths but needs a thorough explanation:
- The formula sheet: Provides students with the formula on hand for reference.
- Step-by-step breakdowns: Works through problems slowly, demystifying the process.
- Practice questions: Let students consolidate the skill.
- Printable PDF: Perfect for revision, reference in tests, or for classwork examples.
This resource isn't just about remembering the formula. It focuses on the 'how' and 'why' to give students a deep understanding of how the formula works.
Also, have a look at our wide range of worksheets that are specifically curated to help your students practice their skills related to quadratic formulas. These teaching resources and worksheets are in PDF format and can be downloaded easily.
