Answer:
No
Step-by-step explanation:
Given factors : (x + 2)(x - 1)
To find the zeroes, these factors should be equal to zero.
Using zero product rule.
→ (x + 2) = 0 and (x - 1) = 0
→ x = - 2 and x = 1
Given zeroes are - 1 and 2, which are wrong.
Therefore, - 1 and - 2 are not the zeroes of the polynomial which has (x + 2) and (x - 1) as factors.
