Question

check whether
(-1/2) is a zero of the polynomial
P(Y)=2y +1​

Answer 1

Step-by-step explanation:

$p(y) = 2( \frac{ - 1}{2} ) + 1 \\ = \frac{3}{2} + 1 \\ \frac{3 + 2}{2} \\ \frac{5}{2}$

Answer 2

Answer:

yes

Step-by-step explanation:

substitute (-1/2) in place of y in equation

so

p(y)=2*(-1/2)+1

= (-2/2)+1

= -1+1

= 0

so it is a zero for above equation
