s(s-1)=2 What are the solutions to the given equation? Choose 1 answer: (A) s=-2 and s=1 (B) s=0 and s=-1 (C) s=0 and s=1 (D) s=2 and s=-1

Write Equation and Set Zero: Write down the given equation and set it to zero by moving all terms to one side. s(s - 1) = 2 s^2 - s - 2 = 0Factor Quadratic Equation: Factor the quadratic equation. We look for two numbers that multiply to -2 and add up to -1. The numbers -2 and 1 fit this requirement. (s - 2)(s + 1) = 0Solve for s: Set each factor equal to zero and solve for s. s - 2 = 0 or s + 1 = 0 s = 2 or s = -1
