Question

Find the number of zeros of the given polynomials. And also find their values.(i) p(x) = 2x + 1 (ii) q(y) = y² – 1 (iii) r(z) = z³

Answer 1

Step-by-step explanation:

to find zero put equation =0 and number of zeroes=degree of polynomial

Answer 2

Answer:

i)p(x)=2x+1

2x+1=0

x= -1/2

is 0 of p(x)

ii)q(y)=y square -1

y square -1 =0

y square= 1

y=1

y=1,-1 are zeros of q(y)

iii)r(z)=z cube

z cube=0

z=0,0,0 are zeros of r(z)
