Let us assume that lucky number is x.

Now, as ‘x’ is made 4 times of itself, it grows to ‘4x’ . (That’s Great)

Now ‘4x’ is added to the square of ‘x’, it results in ‘4x + x ^2’ (Wohh, that’s big)

Now, this is equal to 96.

Therefore,

4x + x^2 = 96

Writing it in proper quadratic form

Answer 2

Answer:

$4x + x^2 = 96$

Explanation:

Quadratic Equation-As well as being a formula that yields the zeros of any parabola, the quadratic formula can also be used to identify the axis of symmetry of the parabola, and the number of real zeros the quadratic equation contains.

Solving way-

1. Now, as ‘x’ is made 4 times of itself, it grows to $4x$ .

2. Now ‘4x’ is added to the square of ‘x’, it results in $4x + x ^2$

3. Now, this is equal to 96.

So

$4x + x^2 = 96$
