missing parantheses in denominator in math book formula for quadratic ecuations

[Former user]

in the math book tab under quadratic equations the formulas are written as: x1=(-b + sqrt(b^2 - 4ac))/2a x2=(-b - sqrt(b^2 - 4ac))/2a

this causes the entire numerator to be divided by 2 and then multiplied by a the correct formulas would be: x1=(-b + sqrt(b^2 - 4ac))/(2a) x2=(-b - sqrt(b^2 - 4ac))/(2a)
