Expanding Brackets
Expanding fractions
The different types of brackets are: * round brackets, open brackets or parentheses: ( ) * square brackets, closed brackets or box brackets: [ ] * curly brackets, squiggly brackets, swirly brackets, braces, or chicken lips: { } * angle brackets, diamond brackets, cone brackets or chevrons: < > or ⟨ ⟩
Brackets means to work out whatevers inside the brackets before you work out anything else!
Brackets are a way of ordering the priority of operations. In mathematics, usually things with brackets have their operations completed first.
Expanding Brackets
It is the opposite of Expanding The Brackets
the opposite of expanding
It is equivalent to 6-27m after expanding the brackets
Contracting
The only opposite of abbreviation is writing out, or expanding the abbreviation.
Expanding the brackets: 6x+21 = 3(2x+7)
The opposite of expand is contract (in some uses, to shrink).For expand (increase), the opposite can be reduce or decrease.For expand (widen), the opposite would be to narrow.For expand (inflate) the opposite would be to deflate.
Expanding fractions
Answering and algebraic equation by expanding what's in the brackets is also called factoring. Factoring perfect square trinomials or other types of equations are done differently, but I'll show you a basic example. 1. First multiply all the terms in the second set of brackets by the first term in the fist brackets. So y x y and y x -3 which will give you y (y+6)(y-3)
Usually they are opposite processes. Factorisation is taking an algebraic expression and partitioning it into factors in brackets (or parentheses). Expansion is taking such brackets and multiplying them out to a simple - if lengthy - expression.
A straight line.
