« Question 42: Simplify the expression: \( C = 9{x^2} – 2xy + \frac{1}{9}{y^2} – 2\left( {3x – \frac{1}{3} y} \right)\left( {3x + \frac{1}{3}y} \right) + {\left( {3x + \frac{1}{3}y} \right)^2}\)

Question 43: Simplify the expression: \( A = \left( {{x^2} – 3x + 9} \right)\left( {x + 3} \right) – \left( {54 + {x^) 3}} \right)\) »
