Q. 3x2+4xy23x^{2}+4xy^{2}\newlineWhich of the following is equivalent to the given expression?\newlineChoose 11 answer:\newline(A) x(3x+4y)x(3x+4y)\newline(B) x(3x+4y2)x(3x+4y^{2})\newline(C) x2(3+4y)x^{2}(3+4y)\newline(D) x2(3+4y2)x^{2}(3+4y^{2})
  1. Factor Expression: We need to factor the expression 3x2+4xy23x^{2}+4xy^{2} to see if it matches any of the given options.
  2. Identify Common Factors: First, we look for common factors in both terms. The term 3x23x^{2} has a factor of xx, and the term 4xy24xy^{2} also has a factor of xx.
  3. Factor Out Common Factor: We factor out the common xx from both terms: x(3x)+x(4y2)=x(3x+4y2)x(3x) + x(4y^{2}) = x(3x + 4y^{2}).
  4. Compare with Options: Now we compare the factored expression x(3x+4y2)x(3x + 4y^{2}) with the given options:\newline(A) x(3x+4y)x(3x+4y) - This is not equivalent because the yy term is not squared.\newline(B) x(3x+4y2)x(3x+4y^{2}) - This is equivalent to our factored expression.\newline(C) x2(3+4y)x^{2}(3+4y) - This is not equivalent because the xx term is squared in the second factor.\newline(D) x2(3+4y2)x^{2}(3+4y^{2}) - This is not equivalent because the xx term is squared in the second factor.
  5. Correct Answer: The correct answer is (B) x(3x+4y2)x(3x+4y^{2}), which is equivalent to the given expression 3x2+4xy23x^{2}+4xy^{2}.
