Question

) VERIFY ZERO OR NOT- P(X)=3X+1,X=-1/3
P(X)=(X+1) (X-20) ?​

Answer 1

VERIFY ZERO OR NOT- P(X)=3X+1,X=-1/3

P(X)=(X+1) (X-20) ?

Answer 2

Step-by-step explanation:

Q. Verify X = -1/3 , is the zero of P (X ) = (X +1) (X-20 )...

Solution ;

Let , us take X = - 1/3

Now , P ( X ) = ( X + 1 ) ( X - 20)

=> ( -1/3 + 1) ( -1/3 -20)

= (-1+3/3 ) ( -1-60/3)

= 2/3 × (-61/3) = - 122/9 is not equals to zero

Verification ;

As we can see that by taking x = -1/2 ..we haven't got zero so it's not the zero of the polynomial .

Hope ! it's helpful...
