Question

Which shows the correct substitution of the values a, b, and c from the equation 1 = –2x + 3x2 + 1 into the quadratic formula?

Answer 1

a = 3, b = - 2 , c = 0

Explanation:

The equation is

`1 = - 2 x + 3 x^2 + 1 \\\\3 x^2 -2x +0 = 0`

By comparing with the standard equation

`ax^2 + bx + c = 0`

So,

a = 3, b = - 2 , c = 0
