Z.z Divi ser by (a) Multiply se 3 by se 4. (b) Divide sel by x. (c) Add sel to se3. 12.3 Create the following symbolic equations: (a) sql = x^2 + y^2 = 4 (b) sq2 = 5*x^5 4*x^4 + 3*x^3 + 2*x^2 - x = 24 (c) sq3= sin (a) + cos (b) -x*c = d (d) sq4 = (x^3 -3*x)/(x-3) = 14 12.4 Try to use the numden function to extract numerator and denomina se4 and sq4. Does this function work for both expressions and eq Describe how your results vary. Explain the differences. 12.5 Use the expand, factor, collect, and simplify functions on se4, and on sql to sq4. In your own words, describe how these fur work for the various types of equations and expressions.
