Answer 2

Answer:

Step-by-step explanation:

Move all terms containing b to the left, all other terms to the right. Add '81' to each side of the equation. -81 + 81 + b 2 = 0 + 81 Combine like terms: -81 + 81 = 0 0 + b 2 = 0 + 81 b 2 = 0 + 81 Combine like terms: 0 + 81 = 81 b 2 = 81 Simplifying b 2 = 81 Take the square root of each side: b = {-9, 9}
