A pool is being filled with a large water hose. The height of the water in a pool is determined by 8g 2+3g-4. Previously, the pool had been filled up with a different hose. Then, the height was determined by 6g 2 +2g-1. Write an expression that determines the height of the water in the pool if both hoses are on at the same time. Simplify the expression.
