The quadratic has been factorised Note that you should never get these wrong because the answer can always be checked by multiplying-out the brackets again! Example Suppose we want to factorise the quadratic expression x2 ?7x+12 Starting as before we look for two numbers which multiply together to give 12 and add together to give ?7
Worksheet 2:6 Factorizing Algebraic Expressions Section 1 Finding Factors Factorizing algebraic expressions is a way of turning a sum of terms into a product of smaller ones The product is a multiplication of the factors Sometimes it helps to look at a simpler case before venturing into the abstract The number 48 may be written as a product in a
In this unit we will look at how to solve quadratic equations using four methods: • solution by factorisation • solution by completing the square • solution using a formula • solution using graphs Factorisation and use of the formula are particularly important 2 Solving quadratic equations by factorisation
