Question 1047090
i believe the underlined should be replaced with "in standard form".


standard form is ax^2 + bx + c = 0


in order to use the quadratic formula, the equation has to be converted to standard form.


once in standard form, you get:


a is the coefficient of the x^2 term.
b is the coefficient of the x term.
c is the constant term.


the quadratic formula is x1 = {{{(-b+sqrt(b^2-4ac))/(2a)}}} and x2 = {{{(-b-sqrt(b^2-4ac))/(2a)}}}


this can also be written as:


x = {{{(-b+-sqrt(b^2-4ac))/(2a)}}} 


you would simply replace a,b,c from the equation into the formula and solve for x.


here's a reference on standard form of a quadratic equation.
