Write the quadratic equation in standard form with the coefficient of x2 positive. Name the values of a, b, and c. x^2 = 3 x +8

OpenStudy (campbell_st):

well simply subtract 3x and 8 from both sides of the equation and you get \[x^2 -3x - 8 = 0\] the standard form is \[ax^2 + bx + c = 0\] so macth your equation to the standard form to find a, b and c

OpenStudy (anonymous):

you need it in quadratic form?

OpenStudy (anonymous):

yes
