Question

I have difficulty in question 3

Answer 1

Answer:

cubic polynomial=

(X)cube-{6x} square-x-30

Answer 2

Step-by-step explanation:

zeroes of polynomial are 5,3,–2

sum of zeroes=5+3+(–2)=6

sum of zeroes taken two at a time=5×3+3×(–2)+(–2×5)= –1

product of zeroes=5×3×(–2)=–30

substitute values in

《k(x^3–x^2(sum of zeroes)–x(sum of zeroes taken 2 at a time)+product of zeroes)》

K(x^3 –x^2(6)–x(–1)+30)

K(x^3–6x^2+x–30) (( k=1)

x^3‐6x^2+x–30 is cubic polynomial
