Sum of the roots
Web12 Apr 2024 · sum of roots = -b/a where a and b are the coefficients of x^2 and x, respectively. Comparing the given equation with the standard form ax^2 + bx + c = 0, we can see that a = 122 and b = -7. So, the sum of the roots of the equation 122x^2 – 7x + 4 = 0 is: sum of roots = -b/a = - (-7) / 122 = 7/122 WebFor some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only …
