GCSE Secondary Maths Age 13-17 - Algebra: Algebra - Explained

The video tutorial explains how to express a polynomial in the form of ax^3 + bx^2 + cx + d, where a, b, c, and d are positive integers. It demonstrates the expansion of triple brackets, starting with the first two and then incorporating the third. The process involves collecting like terms and ensuring all coefficients are positive integers. The tutorial also outlines the marking scheme for the problem, emphasizing the importance of each step in the expansion process.

What is the general form of a cubic polynomial as mentioned in the text?

Explain the process of expanding the first two brackets in the polynomial.

Describe how to collect like terms after expanding the polynomial.

What are the final coefficients A, B, C, and D in the expanded polynomial?

What marks were allocated for the different parts of the polynomial expansion question?
