HOW TO DETERMINE ABC FORMULA

Square equations of universal is “a” times x square plus “b” times x plus “c” equals zero. And then, if we want to difference square equation of universal.
With all over coeffisien with “a” and then we will piocure x square plus “b’ over “a” times x plus “c’ over “a” equals zero. And then we are plus to second internade with “b” square over open bracket four times “a” square close bracket. So be can equation is x square plus “b” over “a” square plus “b” square over open bracket four times “a” square close bracket equals “b” square over open bracket four times “a” square close bracket. We will a group to x plus open bracket two “a” close bracket equals b square over four “a” square minus c over a equals b square minus four times “a” times “c’ in bracket all over four times a square in bracket. So, be can x plus “b” over open bracket two times “a” close bracket equals plus minus “b” square minus four times “a” times in bracket all over open bracket four times “a” square in bracket square root. So, we will x equals minus b plus minus open bracket “b” square minus four times “a” times “c” in bracket square root close bracket all over open bracket two times “a”. So, we can abc formula is x equals minus “b” plus minus open bracket “b” square minus four times “a” times “c” in bracket square root close bracket all over open bracket two times a close bracket.
