Answer:
Option B
Step-by-step explanation:
For this we'll put all of these options in place of x
Number 1:
=> [tex]2(2)^2+7(2)-4[/tex]
=> 2(4)+14-4
=> 8+10
=> 18
So, This is not the zero of the polynomial
Number 2:
=> [tex]2(1/2)^2+7(1/2)-4[/tex]
=> 2(1/4)+7/2-4
=> 1/2+7/2-4
=> [tex]\frac{1+7-8}{2}[/tex]
=> [tex]\frac{8-8}{2}[/tex]
=> 0
Yes, This is the zero of the polynomial having zero as an answer
So, We'll end the solution here because we have found the zero of the polynomial.
Hope this helps :)
