gary, Heather, and Irene want to find the zeros of the polynomial P(x). They evaluate the polynomial for different values and find: P(βˆ’1)=0 P(0)=1 P(2+3β€“βˆš)=0 Each student interprets this information separately and presents his or her conclusions to the group. Gary concludes that since P(βˆ’1) and P(2+3β€“βˆš) equal 0, 2 zeros of P(x) are βˆ’1 and 2+3β€“βˆš. By the Irrational Root Theorem, 2βˆ’3β€“βˆš is also a zero of P(x). Heather concludes that since P(0)=1, 1 zero of P(x) is 1. There isn't enough information to determine any other zeros of P(x). Irene concludes that since P(βˆ’1) and P(2+3β€“βˆš) equal 0, 2 zeros of P(x) are βˆ’1 and 2+3β€“βˆš. There isn't enough information to determine any other zeros of P(x). Which statements correctly explain why each student is correct or incorrect?
