Change the subject where the unknown appears twice in an algebraic fraction
In this lesson, we will be changing the subject of a formula in which the unknown appears twice, involving algebraic fractions.
Expand linear and quadratic expressions
In this lesson, we will multiply a quadratic expression by a linear expression.
Expand product of more than two binomials
In this lesson, we will multiply more than two binomials together. We will use the grid method to calculate algebraic multipllication using 3 pairs of brackets.
