x^2+7x+6=0. Factorise the quadratic equation

x2+7x+6=0First identify factors of 66x1=63x2=6Then look at these pair and see if either of the can be added/subtracted from each other to give the value of 7. Therefore you would use 6+1=7These will then be the values you use in the brackets and can factorise to:(x+6)(x+1)=0
