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?

Ineed asap. 35 points. in order for two polygons to be similar, two conditions must be met. first, all pairs of corresponding sides must be in proportion. second, all corresponding angles must be congruent. prove that angle congruence is not enough, by itself, to establish that two polygons are similar. do this by describing or drawing two polygons that are not similar but whose corresponding angles are all congruent.
