Question

Verify whether the following are zeroes of the polynomial, indicated against them for

p(x) = (x + 1) (x - 2), x = -1, 2​

Answer 1

Answer:

Try replacing -1 , 2 in place of x

Step-by-step explanation:

p(-1)= (-1 + 1 ) ( -1 - 2 )

= ( 0 ) ( -3 )

= 0

p(2) = ( 2 +1 ) ( 2 - 2 )

= (3)(0)

= 0

Therefore , yes -1 and 2 are zeroes of the following polynomial
