Question

p(x)=2x+1;x= -1/2
verify weather the values of x given in each case are the zeros of the polynomial or not?​

Answer 1

Answer:

$given \: p(x) = 2x + 1$

$x = \frac{ - 1}{2}$

$p( \frac{ - 1}{2} ) = 2( \frac{ - 1}{2} ) + 1$

$p( \frac{ - 1}{2} ) = - 1 + 1$

$p( \frac{ - 1}{2} ) = 0$

$so \: x = \frac{ - 1}{2} \: is \:the \: \: zero \: of \: p(x)$

Answer 2

Answer:

P(x)=2x+1

So

P(-1/2)=2×(-1/2)+1 = - 1+1 = 0

So - 1/2 is the zero of P(x)
