y=(x+3)^2+(x+4)^2

First expand to a quadratic

y=2x^2+14x+25

next divide by the leading coefficient (2), or rather factor out the leading coefficient:

y=2[x^2+7x+12.5]]

Complete squares on the expression inside brackets

y=2[(x+3.5)^2-12.25+12.5]

=2[(x+3.5)^2+0.25]

=2[(x+3.5)^2+0.25]

Distribute:

y=2(x+3.5)^2+0.5

The last line above is the vertex form of the same parabola.

The vertex form of the given parabolic equation is [tex]y=2(x+3.5)^2+0.5[/tex] and it can be determine by simplifying and then rewriting the given equation in vertex form of parabola.

Given :

Equation - [tex]y = (x+3)^2+(x+4)^2[/tex]

The given equation represents a parabola and the vertex form of parabola is given by:

[tex]y=a(x-h)^2+k[/tex]  --- (1)

Now, simplify the given equation as:

[tex]y = x^2+9+6x+x^2+16+8x[/tex]

[tex]y = 2x^2+14x+25[/tex]  ---- (2)

Now, rewrite the equation (2) in form of equation (1).

[tex]y = 2(x^2+7x+12.5)[/tex]

[tex]y = 2((x+3.5)^2-12.25+12.5)[/tex]

[tex]y=2(x+3.5)^2+0.5[/tex]

Therefore, the vertex form of the given parabolic equation is [tex]y=2(x+3.5)^2+0.5[/tex]
