प्रश्न
Verify whether the indicated numbers is zeroes of the polynomials corresponding to them in the following case:
`f(x)=x^2- 1,x=1,-1`
Advertisements
उत्तर
`f(x)=x^2- 1,x=1,-1`
we have `f(x)x^2 -1`
put `x=`and `x=-1`
`⇒ f(1)=(1)^2 -1` and `f(-1)=(-1)^2-1`
`=1-1=0` `=1-1=0`
`∴=1,-1`are the roots of `f(x)=x^2-1`
