group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

i dont know the answer but here's a picture of a dog

the one below it is a function

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
