Question 363878: A gardener wants to create a triangular garden in the shape of a right triangle with shortest side length x – 6y ft. and the middle length side x + 6y ft. What is an algebraic expression for the area of the garden? Be sure to multiply this out and express in simplest correct mathematical form, including units.
I thought I had this until I looked at the formula for a right triangle
This is what I have
(x-6y)(x+6y) using FOIL
= x^2 - 36y^2 ft But how does this fit with a^2 + b^2 = c^2
Would I divide x^2 - 36y^2 by 2? I am so confused.

Question 364534: Use synthetic division to verify the upper bound and lower bound of the zeros of f.
f(x) = 2x^4 -8x +3
Upper bound: x= 3; Lower bound: x= -4
The quotient I found for the upper bound was 2x^3 + 6x^2 + 18x + 46 + 136/ x-3
I have no idea if this is right and I am not sure where I would need to go from here.
