Question

What is the vertex form of `y= x^2 + 10x +25`?

Answer 1

`y=(x+5)^2`

Explanation:

Given : `y=x^2 +10x+25`
`y = (x+5)^2`
This is the vertex form of the equation of curve denoted by the latter.
Definition : vertex form of a parabola is given by
`y= a(x-h)^2 + k`
where (h,k) is the vertex of the parabola and `x-h=0` is the axis of symmetry .
