2x^3 - 3x^2 + 4x - 3

It's a polynomial of degree 1.

The highest power of the variable is 2, so it is a second degree polynomial.

I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.

no 3x2=6 then 4x-15= -60 so 6 added with - 60 = -54

3x2 + 2x - 8 = 3x2 + 6x - 4x - 8 = 3x(x+2) - 4(x+2) = (3x-4)*(x+2)

Yes. -4x is one, and 3y is one. They are combined with a "+" sign, and together they are a polynomial.

no 3x2=6 then 4x-15= -60 so 6 added with - 60 = -54
