Question

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

Answer 1

subtract -1 on both sides to get equation into standard form
2x^2 - 4x + 5.
The C value would be 5

Answer 2

c = 5

Explanation:

Given equation
`2x^2 - 4x + 6 = 1`

We have to Write the equation
`2x^2 - 4x + 6 = 1` in standard form and then choose the value of "c."

The standard form of the quadratic equation is given as
`ax^2=bx+c=0`, where a , b and c are the coefficients.

Consider the given equation
`2x^2 - 4x + 6 = 1`

Subtract 1 both sides, we have,

`2x^2 - 4x + 6-1=1-1`

simplify, we have,

`2x^2 - 4x + 5=0`

Now on comparing with standard form we get,

a = 2 , b = -4 and c = 5

Thus , c = 5
