A quadratic equation is of the form ax^2+bx+c=0 There are three ways to solve a quadratic equation: 1)Factorising- this is where you find two numbers that multiply to give c and add to give b ie. x^2+5x+6=0 the numbers 2 and 3 multiply to gove 6 and add to give 5 so we can put this equation into a factories form of (x+2)(x+3)=0 this means x=-2 and x=-3 are solutions to this equation. If the Equation has a coefficient for x^2 that's is greater than 1 then you can use the ac method where you first multiply ac then split bx into the two identified numbers and then factories them separately 2)Complete the square to put the equation into the form a(x+p)^2+q then to rearrange for x 3) Quadratic formula
