Question

verify whether x= -1/2 is the zero of polynomial g(x) =2xsquare+x-1​

Answer 1

Answer:

Step-by-step explanation:

We are given that x= -1/2

For the polynomial 2x²+x-1

By middle term split

2x²+x-1

2x²+2x-1x-1

2x(x+1)-1(x+1)

(2x-1)(x+1)

We get the values of x as 1/2 and -1.

So clearly we can say that x=-1/2 is not a zero of polynomial 2x²+x-1.
