in matlab plz

Required File: Program_Sym_2.m Use symbolic expressions to complete the problem pictured below. After factoring in part a, solve the equation to confirm that the roots are as given. In part b, show the polynomial in standard form using the pretty function Solve the equation in part b to confirm the roots are as given. Please ensure your output matches the example output. 4. Define x as a symbolic variable. a) Show that the roots of the polynomial: f(x)=x5x427x3+13x2+134x120 are 1,2,5,3, and -4 by using the factor command. b) Derive the equation of the polynomial that has the roots: x=5,x=3, x=2, and x=4. Example Output: Output for Program_12_2 written by Geoff Berl. Part a: Original Function f Defined f= x5x427x3+13x2+134x120 f=factor(f) f= [x1,x2,x+4,x+3,x5] X=solve(f) x= Empty sym: 0 by-1 Part b: Original Function g Defined g= (x+2)(x+3)(x4)(x5) g=expand(g) g= x44x319x2+46x+120 pretty(g) x4x19x+46x+120 x=solve(g) x= 3 2 4
