अथवा/OR​

Answer 1

Answer:

Ascending Order:-

1.9,4.5,5.1,5.4

Descending Order:-

8.7,4.9,4.7,3.8

Step-by-step explanation:

Givn polynomial

Toverify: x=2 is a zero of the given polynomial

Solution:

Consider

${x}^{2} - 5x + 6 \\(2) {}^{2} + 5x + 6 \\ = > 4 + 5(2) + 6 \\ = > 4 + 10 + 6 \\ = > 14 + 6 \\ = > 20$

Thus,x=2 is a zero of the polynomial

${x}^{2} + 5x + 6$

n=20.
