2x^2-5x+2=0, You need not apply any formula here Straight away you can form the equation ×+1/×= 4+1/4,this gives ×=4or 1/4, very easy Only when in a×^2+b×+c b=-a^2+1 or b= - c^2+1, a=c Mukund
@@MathlessonswithLinda As a math tutor, who has used the method you showed and one other, all that work, Mr's H's method is the easiest. I taught the other two methods for years and then saw Mr. H's and realized it's the easiest. I always look for the easiest way for my students.
