Expanding pairs of brackets
In this article we are going to have a quick look at how to expand pairs of brackets such as (x + 1)(x + 3) or (x − 5)(3x + 2). This is an important skill in high school/GCSE maths and one which often appears in algebraic problem solving, so it's important to have a good understanding of the basics. See more One good way to gain an understanding of this topic is to think about what it means when we multiply two brackets. If we look at (x + 1)(x + 3), we have an unknown with one added to it and … See more To find the area, we have split each side of the rectangle into its x component and the integer component. This has created 4 smaller rectangles … See more We now multiply out each of the pairings as so: x × x = x2 x × 1 = x 3 × x = 3x 3 × 1 = 3 Collecting these together gives x2+ x + 3x + 3. We now simplify by collecting like terms (any terms with the same power of x) and so add … See more The pictorial method shown above is a great way to picture the problem and gain some understanding of what is happening, but we can be much … See more WebWe can also expand pairs of brackets. To expand the expression \((a+b)(x+y)\), we must multiply every term in the first bracket by every term in the second. Hence, \begin{align*} (a+b)(x+y) &=a(x+y)+b(x+y)\\ &=ax+ay+bx+by. \end{align*} Expressions such as this, involving a pair of brackets each containing two terms, are sometimes referred to as ...
