Question

Write the degree of the following polynomials:
a) -x 2 +5x
b) 4x 2 y+5xy-6
c) 3x 2 -2xy 2 -5xy

Answer 1

Answer:

A)The degree is the value of the greatest exponent of any expression (except the constant) in the polynomial.

Given: 5x

2

−3x+2 (is a polynomial in x)

The greatest exponent of x in the expression is 2

B)We have

(i) 3x + 7x = (3 + 7)x = 10x

(ii) -5xy + 9xy = ( -5 + 9)xy = 4xy
