Alessandro wrote the quadratic equation -6=x2+4x-1 in standard form. what is the value of c in his new equation?
c=-6
c=-1
c=5
c=7

c = 5

Step-by-step explanation:

A quadratic expression is an expression of the form

ax^2 + bx + c = 0

If we rewrite the expression, we get

-6=x^2+4x-1

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

x^2+4x +5 = 0

The answer is c = 5

The correct answer is third option

c = 5

Step-by-step explanation:

Points to remember

Standard form of a quadratic equation

ax² + bx + c = 0

It is given that, -6 = x² + 4x - 1

To find the standard form

-6 = x² + 4x - 1

⇒   x² + 4x - 1 = -6

x² + 4x - 1 + 6= 0

x² + 4x + 5 = 0

To find the value of c

Let equation be,  x² + 4x + 5 = 0

Here a = 1, b = 4 and c = 5

Therefore the correct answer is third option

c = 5
