Question

Define x andy as symbolic variables and create the two symbolic expressions $$S = x + \sqrt { x } y ^ { 2 } + y ^ { 4 }$ and T = \sqrt {x} - y ^ { 2 }T= x−y 2 $Use symbolic operations to determine the simplest form of S \cdot⋅ T . Use the
subs command to evaluate the numerical value of the result for x = 9 and
y = 2 .
