A pool is being filled with a large water hose. The height of the water in a pool is determined by 8g² + 38 – 4. Previously,
the pool had been filled with a different hose. Then, the height
was determined by 6g² + 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
