Question

Rewrite y = x2 + 14x + 29 in vertexform.

Answer 1

u know the vertex form ?

Answer 2

y = a(x - h)2 + k, but how do I rewrite it like this?

Answer 3

first observe that a will be 1, because it will be the co-efficient of x^2.(and in question, co-efficient of x^2 is 1)
now, u have to complete the square , u know how ?
