A pool is being filled with a large water hose. The height of the water in a pool is determined by 8g^2 + 2g- 3. Previously, the pool had been filled with a different hose.
Then, the height was determined by 5g^2 + 2g - 1. Enter an expression that determines the
height of the water in the pool if both hoses are on at the same time. Simplify the
expression.
An expression that determines the height of the water in the pool if both hoses are on at
the same time is .
