Exercise 4.4 – Square Roots and Applications of Polynomials This exercise focuses on finding the square roots of polynomials and applying polynomial factorization to real-life mathematical models. Questions 1 and 2 develop skills in finding the square root of polynomial expressions using the factorization method and the division method. Questions 3 to 6 apply polynomial concepts to practical situations involving investment returns, business profit, potential energy, and structural deflection. Students are required to factorize given expressions and determine the values of the variable for which the result is zero. Students should carefully apply the appropriate method, show complete working steps, and interpret results correctly. This exercise strengthens both algebraic techniques and their applications in real-world problems.
