Can anyone help me with this answer:

Mathematics
1 answer:
lianna [129]3 years ago
4 0

Answer:

Option B

Step-by-step explanation:

For this we'll put all of these options in place of x

<u><em>Number 1:</em></u>

=> 2(2)^2+7(2)-4

=> 2(4)+14-4

=> 8+10

=> 18

<u><em>So, This is not the zero of the polynomial</em></u>

<u><em>Number 2:</em></u>

=> 2(1/2)^2+7(1/2)-4

=> 2(1/4)+7/2-4

=> 1/2+7/2-4

=> \frac{1+7-8}{2}

=> \frac{8-8}{2}

=> 0

<em><u>Yes, This is the zero of the polynomial having zero as an answer</u></em>

<em>So, We'll end the solution here because we have found the zero of the polynomial.</em>

Hope this helps :)
