Evaluate 7 r − 15 s 7r− s 15 7, r, minus, start fraction, 15, divided by, s, end fraction when r = 3 r=3r, equals, 3 and s = 5 s=5s, equals, 5.

33

Step-by-step explanation:

-297

Step-by-step explanation:7*3-15*7*3-(15)/(5)

7*3=21

-15*7=-105

-105*3=-315

-15/5=-3

21-315-3

21-315=-294

-294-3=-297

Answer with Step-by-step explanation:

Degree of polynomial equation depends on the number of linear factor.

If x-a, x-b, x-c are three linear factors then multiply these factors then we get

Degree of polynomial =3

If there are one factor, then degree of polynomial is 1 and the polynomial equation is linear.

If there are two factors then, the polynomial is quadratic and degree of quadratic polynomial is 2.

If there are three linear factors then, the degree of polynomial equation is 3 and it is cubic polynomial.
