Learn how to factor polynomials by grouping. A polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, ...

👉 Learn how to simplify identities by factoring. Just like in normal algebraic expressions, trigonometric identities can be ...

Simplify \(\frac{3t + 6}{3t}\). The numerator of this fraction will factorise as there is a common factor of 3. This gives \(\frac{3(t + 2)}{3t}\). Now, there is clearly a common factor of 3 between ...

In a quadratic expression, the highest power of \(x\) is \(x^2\). Factorise \(x^2 + 7x + 10\). To factorise this expression, find two numbers that have a product of +10 and a sum of +7. There are four ...
