Which algebraic expression is a polynomial with a degree of 5?

a) 3x5 + 8x4y2 - 9x3y3 - 6y5

b) 2xy4 + 4x2y3 - 6x3y2 - 7x4

c) 8y6 + y5 - 5xy3 + 7x2y2 - x3y - 6x4

d) - 6xy5 + 5x2y3 - x3y2 + 2x2y3 - 3xy5

The answer is B!

The answer is;

B) 2xy4 + 4x2y3 - 6x3y2 - 7x4

2xy4 + 4x2y3 - 6x3y2 - 7x4; The Degree is 5 if you look at the 1st, 2nd, and 3rd terms.

The degree of a polynomial is the highest exponent/sum of exponents of the variables in the individual terms of a polynomial.
