Answer:
there is a video called the pi song
just basic value is 22/7 or 3.14
<span>The quadratic formula is the solution of the quadratic equation. There's other ways to solve it, but the quadratic formula the easiest/most convenient.

The given expression is:

So, there are two terms in the expression
1)

2) -5
The constant term is -5.
The co-efficient of

is 4.
f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.
Do you see the h and k in your equation?
-h = -(-2) = 2
We see that k = -4.
Our vertex is (2, -4).
