Select all of the expressions that are equivalent to:
A.) (3x²  y)²
B.) (3x²)²  (y)² C.) 9(x²)²  (y)² D.) (9x²)²  (y)² E.) (3x² + y)(3x²  y)
Just evaluate each answer choice to see if it is a match.
A.) (3x²  y)² → (3x²  y)(3x²  y) → 9x^4  6x²y + y² {used foil method} B.) (3x²)²  (y)² → 9x^4  y² {evaluated exponents} C.) 9(x²)²  (y)² → 9x^4  y² {evaluated exponents} D.) (9x²)²  (y)² → 81x^4  y² {evaluated exponents} E.) (3x² + y)(3x²  y) → 9x^4  y² {used foil method} B.) , C.) , and E.)  Algebra House Comments are closed.
