Nick is solving the equation 3x^2=20-7x with the quadratic formula

which values could He use for a, b and c

C. a = 3

b = 7

c = - 20

Step-by-step explanation:

x = - b+ / - (sq) b^2 - 4ac.

Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0

S if you use your equation : 3x^2 = 20 - 7x

First you have to move everything to one side.

So it'll look like this:

3x^2 = 20 - 7x

-20 - 20

3x^2 - 20 = - 7x

+7x + 7x

3x^2 - 20 + 7x = 0

don't forget that ... Ax^2 + Bx + C = 0

3 = A

7 = B

-20 = C
