Answer: y = ±√ 0.500 = ± 0.70711
Explanation:
Solve : 2y2-1 = 0 Add 1 to both sides of the equation : 2y2 = 1 Divide both sides of the equation by 2: y2 = 1/2 = 0.500 When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get: y = ± √ 1/2
