Question

Write the equation 2x 2 - 4x + 6 = 1 in general form and then choose the value of "c."

5
3
2.5

Answer 1

The value of c is 5.

Step-by-step explanation:

The given equation is
`y=2x^2-4x+6=1`

General form of a quadratic equation is given by

`y=ax^2+bx+c=0`

Subtract 1 to both sides of the given equation

`y=2x^2-4x+6-1=0\\y=2x^2-4x+5=0`

Comparing with general equation, we get

a = 2

b = -4

c= 5

The value of c is 5

Answer 2

The general form of a quadratic equation is written as follows:

Ax^2 + Bx + C

Writing the given equation to the said form we do as follows:

2x^2 - 4x + 6 - 1 = 1 - 1
2x^2 - 4x + 6 - 1 = 1 - 1
2x^2 - 4x + 5 = 0

Therefore, the value of C would be 5, first option.
