Q. We want to factor the following expression:9x4+4y2Which pattern can we use to factor the expression?U and V are either constant integers or single-variable expressions.Choose 1 answer:(A) (U+V)2 or (U−V)2(B) (U+V)(U−V)(C) We can't use any of the patterns.
Identify Structure: Identify the structure of the given expression.The given expression is 9x4+4y2. We notice that both terms are perfect squares: (3x2)2 and (2y)2.
Recognize Factoring Pattern: Recognize the factoring pattern. The expression resembles the sum of two squares, which can be written as A2+B2, where A=3x2 and B=2y.
Determine Factoring Possibility: Determine if there is a factoring pattern for the sum of squares.The sum of squares does not factor over the real numbers using the patterns (U+V)2, (U−V)2, or (U+V)(U−V). These patterns apply to the difference of squares, not the sum of squares.
Conclude Pattern Usage: Conclude which pattern, if any, can be used.Since the sum of squares does not have a factoring pattern over the real numbers, we cannot use any of the given patterns to factor the expression 9x4+4y2.
