Carl is deriving the quadratic equation by completing the square. His work at one of the steps is shown. x + b/na = + or - b^2-4ac. Carl is not sure what the value of n is. What value should he use to continue deriving the quadratic equation correctly? A. 1 B. 2 C. 3 D. 4

the correct option is B. 2

Step-by-step explanation:

As given,

x + = ± √b²-4ac

⇒x = - ± √b²-4ac

As e know that the quadratic formula is

x =

So , by comparing with the formula

we get

n = 2

So, the correct option is B. 2

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
