Question

Consider the polynomial p(x)=x^3-5x^2+ 3x-4 what is the sum of squares of zeros of polynomial

Answer 1

Answer:

Step-by-step explanation:

Let a b and c be 2 zeros

a2+b2+c2=(a+b+c)2-2(ab+bc+ca)

a+b+c=-(-5)/1=5

ab+bc+ca =3/1=3

Put both equations in first one

a2+b2+c2=(5)2-2(3)

25-6=21=ans
