Basic Mathematics QUESTION #2858
Question 1
Expand using identity: \((2x + 3y)^2\)
  • \(4x^2 + 9y^2\)
  • \(4x^2 + 6xy + 9y^2\)
  • \(4x^2 + 12xy + 9y^2\)✔️
  • \(2x^2 + 12xy + 3y^2\)
Correct Answer Explanation
Using \((a+b)^2 = a^2 + 2ab + b^2\): \((2x+3y)^2 = (2x)^2 + 2(2x)(3y) + (3y)^2 = 4x^2 + 12xy + 9y^2\).
