Equations, SM-Bank 059 Show that \(x^2=100\) has 2 solutions. (2 marks) Show Answers Only \(\text{See worked solutions}\) Show Worked Solution \(10^2=10\times 10=100\ \ \therefore \ x=10\ \text{is a solution.}\) \((-10)^2=-10\times -10=100\ \ \therefore \ x=-10\ \text{is a solution.}\) \(\therefore x=10\ \text{and }x=-10\ \text{are both solutions of }x^2=100\)
