Question

Alessandro wrote the quadratic equation –6 = x2 + 4x – 1 in standard form. What is the value of c in his new equation?

Answer 1

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

Answer 2

The value of c is
`5`

Explanation:

we know that

The standard form of the quadratic equation is equal to

`ax^(2) +bx+c=0`

In this problem we have

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

Convert to standard form

Equate the quadratic equation to zero

`x^(2)+4x-1+6=0`

`x^(2)+4x+5=0`

so

`a=1\\b=4\\c=5`
