Question

check whether 1 is the zero of the polynomial 9x³-5x+20

Answer 1

Explanation:

No,1 is not the zero of the given polynomial

Answer 2

Answer:-

P(X)=9x^3-5x+20

substitute 1 on the value of x

P(1)=9(1)^3-5(1)+20

       9-5+20=0

        4+20=0

        24=0

: Therefore the answer we are getting is not equal to zero (LHS=RHS)

Therefore ! is not the zero of the polynomial 9x^3-5x+20

Hope this helps Everyone!!!!!
