1. simplify and write in standard form. then, classify the polynomial by degree and number of terms.
(5x^3 + 3x^2 - 7x + 10) - (3x^3 - x2 + 4x - 1)

is it 2x^3+4x^2-11x+11

Respuesta :

Yes, the answer is 2x^3+4x^2-11+11

Answer:

The Standard form of a polynomial is in the form of:

[tex]a_nx^n+a_{n-1}x^{n-1}+.....+a_2x^2+a_1x+a_0[/tex]

i.e,  the highest exponent goes first until the last term with the lowest exponent.

Degree of a polynomial is the highest exponent, and the coefficient of this term is the leading coefficient. The constant term is the one without an x variable.

Simplify: [tex](5x^3 + 3x^2 - 7x + 10) - (3x^3 - x^2 + 4x - 1)[/tex]

Remove the parentheses we get;

[tex]5x^3 + 3x^2 - 7x + 10 - 3x^3 + x^2 - 4x + 1[/tex]

Combine like terms, we get;

[tex]2x^3 + 4x^2 - 11x + 11[/tex]

Standard form of a polynomial = [tex]2x^3 + 4x^2 - 11x + 11[/tex] [descending exponent ]

Degree of a polynomial(i.,e highest exponent is from  [tex]2x^3[/tex]) is, 3

Number of terms  = 4 .
