What are the values of a, b, and c in the quadratic formula given the equation 3x^2-x= 4? a. a=3, b=0, c=-4b. a=3, b=1, c=4c. a=3, b=1, c=4d. a=3, b=-1, c=-42. what is the first correct step for solving the equation, x^2+x=12 ?

First question:

First of all, you have to rewrite the quadratic equation bringing everything to the left hand side, so you have

Now, the coefficients of a quadratic equation are usually read as , i.e. is the coefficient of , is the coefficient of and is the constant term.

Once you rewrite your equation, the coefficient of is 3, the coefficient of is and the constant term is , so the correct answer is D.

Second question:

As discussed above, the first step for solving a quadratic equation is bringing everything to the left, so that you are in the form . So, the first thing you have to do is to transform
