Answer:
Answer:y² + 18y - 40 = 0
Answer:y² + 18y - 40 = 0y² + 20y - 2y - 40 = 0
Answer:y² + 18y - 40 = 0y² + 20y - 2y - 40 = 0y(y + 20 ) - 20(y + 20) = 0
Answer:y² + 18y - 40 = 0y² + 20y - 2y - 40 = 0y(y + 20 ) - 20(y + 20) = 0(y + 20)(y - 2) = 0
Answer:y² + 18y - 40 = 0y² + 20y - 2y - 40 = 0y(y + 20 ) - 20(y + 20) = 0(y + 20)(y - 2) = 0y + 20 = 0
Answer:y² + 18y - 40 = 0y² + 20y - 2y - 40 = 0y(y + 20 ) - 20(y + 20) = 0(y + 20)(y - 2) = 0y + 20 = 0y - 2 = 0
