STEP 1 : Find two numbers which add to give you 1 (because of the +x in the middle) and multiply to give you - 6 (because - 1 * 6)
STEP 2 : Input both of these numbers in place of the + x 6x^2 - 2x + 3x - 1 = 0 This is because your 2 numbers are - 2 and 3
STEP 3 : Split the equation into a half and factorise them This will give you : (6x-2) and (2x+1)
STEP 4 : Equal both of these brackets to 0 and make x the subject of both of the 2 formulaes This will give you 6x - 2 = 0 6x = 2 x = 1/3 And 2x + 1 = 0 2x = - 1 x = - 1/2
