Chapter 11, Problem 2P

Define y as a symbolic variable and create the two symbolic expressions

$S_1=x^2(x^3-4x^2+3x+12)-40(x-1)$ and $S_2=(x^2-2x+4)(x-2)$

Use symbolic operations to determine the simplest form of each of the following expressions:

(a) S₁·S_2(b) $\frac{S_1}{S_2}$_(c)S₁-S₂

Use the subs command to evaluate the numerical value of the result from part (c) for x = 6.
