Is this this equation the same with brackets?

Question

is 4x^2+9y^2=36 the same as (x+4)^2+(y+9)^2=36? (if this is a yes i can finish the equation no problem)

If not how would i bring it to Transformational form ... and if it's possible could you explain to me where the different numbers are coming from ?? i already have the answers i just need to learn how to get them.... whats confusing me is where the different numbers come into play. Thanks!

Answer 1

In brief, 4x^2 means 4 times (x * x).

If x=3 say, then you take 3*3 first (=9) times 4.

You can also express as: 4(x^2).

So, NO, your bracketing equation is not the same.
OK, you take it from there.

Answer 2

No, it's not. The first term is 4 times x^2, not square of x + 4 and 9 times y^2, not square of 9 + y.
