A rectangular pool is 25 feet long and 12 feet wide. If the length is increased by 2x what is the new length? How would you use a quadratic equation to solve this?

Since you indicate no change in width and are only asking for the new length, no quadratic equation needed.

2*25 = ?

I was assuming that 2x = two times. If not,

2x + 25 = ?

Still not a quadratic equation.
