Q. We want to factor the following expression:x3−25Which 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 expression: Identify the expression to be factored.The expression given is x3−25. We need to find a pattern to factor this expression.
Recognize pattern: Recognize the pattern applicable for the expression.The expression x3−25 can be seen as a difference of cubes, where x3 is a cube and 25 can be written as 53. Therefore, the expression can be rewritten as x3−53. The pattern for factoring a difference of cubes is (U3−V3)=(U−V)(U2+UV+V2), where U and V are either constant integers or single-variable expressions.
Apply pattern: Apply the pattern to factor the expression.Using the pattern for the difference of cubes, we can factor x3−53 as follows:Let U=x and V=5, then(x3−53)=(x−5)(x2+5x+25).
