We want to factor the following expression: 9x^8 + 6x^4(y + 2) + (y + 2)^2
We can factor the expression as (U + V)^2 where U and V are either constant integers or single-variable
expressions.
1) What are U and V?

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

hope this !

let me know
