Algebraic Techniques, SM-Bank 020 Write an expression for subtracting half of \(x^2\) from the product of \(3\) and \(y\). (2 marks) Show Answers Only \(3y-\dfrac{x^2}{2}\) Show Worked Solution \(\text{Half of }\ x^2=\dfrac{x^2}{2}\ \text{and product }3\ \text{and }y=3y\) \(\therefore\ \text{Subtraction}=3y-\dfrac{x^2}{2}\)
