Question

Find the zeros of the polynomial in each of the following :
(i) p(x) = x – 3 (ii) p(x) = 2x + 5 (iii) q(y) = 2y – 3
(iv) f(z) = 8z (v) p(x) = ax when a ! 0 (vi) h^xh = ax + b, a ! 0, a,b ! R

Answer 1

Solution:-

given by:-

(i) p(x) = x – 3

》p(0) = x-3 = x -3 = 0 = ( x = 3)

》(x = 3) ans

(ii) p(x) = 2x + 5

》p(0) = 2x+5

》0 = 2x+5

》2x = -5

》(x = -5/2) ans

》(x = -5/2)ans

(iii) q(y) = 2y – 3

》= q(0) = 2y -3

》0 = 2y-3

》2y = 3

》(y = 3/2) ans


(iv) f(z) = 8z

》= 0 = 8z
》(z = 0) ans

(v) p(x) = ax when a ! 0

= 0= ax

》= x=0/a

》(x= 0) ans

Answer 2

HY MATE HERE IS YOUR ANSHWER =>

________________________________________________________________________

(i) P(X)=X-3

take x=0

hence

P(0)=x-3

x=3✔ans

(ii) P(x)=2x+5

take x=0

P(0)=2x+5

x=-5/2

i hope it help you☺
