Solving quadratic equations using the factorisation method.
The Form of a quadratic equation where a ≠ 0ax2+ bx + c = 0In order to solve we need to create one term made up of factors.One or more of these factors must equal zero.Questions we will work through:10x2 + 5x = 02x2-x -3 = 04 + 3x = x2x2- 9 = 0Solution Steps:Check if it’s in the correct formCheck to see if it’s got a common factor Factorise accordinglySolve each factor for x = 0
