Question

verify whether the following are zeroes of the polynomial, indicate against them.
1)p(x)=x^2,x=0
2)p(x)=5x-π,x=4/5
3)p(x)=lx+m,x=-m/l
4)p(x)=2x+1,x=1/2​

Answer 1

Step-by-step explanation:

1) p(x)=x^2,x=0

p(0) = (0) ^2= 0

so x=0 js zero of p(X) = x^2

2) p(x)=5x-π, x=4/5

p(4/5) = 5(4/5) -π= 4-π

so x=4/5 is not a zero of p(x) = 5x-π

3) p(x)=lx+m, x=-m/l

p(-m/l) = l(-m/l) +m= -m+m=0

so x= - m/l is zero of p(x) =lx+m

4) p(x)=2x+1, x=1/2

p(1/2)= 2(1/2)+1=1+1=2

x=1/2 is not zero of p(x)= 2x +1
