What are the values of a, b, and c in the quadratic formula given the equation 2x^2 + 6x= -8 ?



a = 2, b = -6, c = -8


a = 2, b = -6, c = 8


a = 2, b = 6, c = -8


a = 2, b = 6, c = 8

Respuesta :

it should be written in the form ax²+bx+c=0,
so you meed to move -8 to the left side
2x²+6x+8=0
the number in front of x²  is a
 the number in front of x is b
the number without x is c,
so a=2, b=6,c=8
