Question

What shows the correct substitution of the values a,b, and c from the equation 0=-3x^2-2x+6

Answer 1

When dealing with a quadratic equation, you usually assign the following name to the coefficients of the variables:

`ax^2+bx+c=0`

So,
`a` is the coefficient of
`x^2`,
`b` is the coefficient of
`x` and
`c` is the constant term.

In your case, the coefficient of
`x^2` is -3, so
`a=-3`

The coefficient of
`x` is -2, so
`b = -2`

The constant term is 6, so
`c = 6`
