WebHow to Expand Brackets. Expanding brackets is an algebraic technique used when solving equations and simplifying expressions.To expand the brackets is to multiply everything inside the brackets, ( ), by what's outside the bracket. For example: 2(x + 3) is 2 multiplied by x added to 2 multiplied by 3. The result is 2x + 6. WebStep 1: Solve the brackets. Follow the order of solving round brackets $( )$ first, then curly brackets $\left\{ \right\}$, and then square brackets $[ ]$. $= 100 − [(2) + (56)]$ $= 100 − 58$ Step 2: No exponent in the given expression. Step 3: No multiplication or division in the given expression. Step 4: Solve the subtraction. $= 100 − ...

Web2 Expand and simplify with two or more brackets. Expand the brackets to give the following expression: E.g. (x + 5)(x − 1) = x 2 + 5x − x − 5 = x 2 + 4x − 5. Remember: expressions with three terms like x 2 + 4x − 5 are known as trinomials. An expression that contains more than two terms and includes variables and coefficients is ...

WebFactorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x - 3 into the form (2x + 3) (x - 1). This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into ...
