Question

verify whether the indicates numbers are zeros of the polynomials (1)p(x) = 3x+1​

Answer 1

i) f(x) = 3x + 1, x = −13−13

 (ii) f(x) = x2 – 1, x = 1,−1  

(iii) g(x) = 3x2 – 2 , x = 23√23 , −23√−23

(iv) p(x) = x3 – 6x2 + 11x – 6 , x = 1, 2, 3  

(v) f(x) = 5x – π, x = 4545

 (vi) f(x) = x2 , x = 0

(vii) f(x) = lx + m, x = −ml−ml

(viii) f

(x) = 2x + 1, x = 12s
