To expand expressions that involve multiplication, follow the rules of the distributive property, which state that any number can be multiplied by any number. This video covers how to expanding triple brackets, so where we have 3 brackets being multiplied together. FOIL stands for "First, Outer, Inner, Last", and refers to the order in which you multiply the terms of the two binomials to get the expanded expression. \begin{eqnarray}
To expand a single bracket we multiply the term outside of the bracket by everything inside of the bracket. Expanding brackets means multiplying everything inside the bracket by the letter or number outside the bracket. \begin{eqnarray}

There is the FOIL method- first, outside, inside, last, or there is the method that I would recommend below: When it comes to double brackets you need to make sure you have multiplied each term in each bracket by each other, therefore: Step 1: Rewrite the expression so you can see that each term in the first bracket will need to be multiplied by each term in the second bracket. There are answers to this exercise but
Remember to highlight the sign in front of the number too! When we square something, we multiply it by itself. Multiply the term outside the bracket (3x) by the second term inside the bracket (2y). Draw a grid, insert the terms from this new expression and the third bracket, then fill it in by multiplying each of the terms together. Translating Algebraic Expressions | Algebraic Expression in Words. Don't wait until you have finished the exercise before you click on the 'Check' button. In order to expand and simplify an expression, we need to multiply out the brackets and then simplify the resulting expression by collecting the like terms.

What is FOIL method? Expand the brackets is the same as multiply out the brackets, it just gives the additional clue that when we expand brackets, we are multiplying everything outside the brackets by everything inside the brackets. Again, we can split the first bracket into its two terms and then multiply each term by the second bracket. Step one: The first step when using the grid method to expand brackets is to draw a grid! Write out each of the terms and simplify the expression by collecting like terms. So x multiplied by x is x squared, x multiplied by 3 is 3x, -5 multiplied by x is -5x, and -5 multiplied by 3 is -15. The answer is positive so we need to write + 12x3.
