in this video were gonna be talking about the fastest way to find Roots so lets say you are writing math exams purely on multiple choice problems and you are giving this question find the root of 2x squared plus 3x minus 2 is equal to zero now since this is a multiple choice problems you dont need the procedures I mean the normal procedures so you want the quickest way you can finish this problem on time so how can we do that this trick is applicable when the coefficient of x squared is greater than one and you can see the coefficient of x squared over here is 2 which is greater than y so we can apply the trick first take the two and then slide it over and multiply it by negative two so were gonna end up getting x squared plus 3x minus 4 is equal to zero now since this is a quadratic equation you end up getting two factors of which your product is equal to zero then you ask yourself what times what will give you x squared we have x times x then you look for two factors that when y
