Question

find degree of the polynomial
( x+2) (x²-2x + 4)​

Answer 1

Your Solution:

Given that,

(x + 2)(x² − 2x + 4)

⇒x(x² - 2x + 4) + 2(x² - 2x + 4)

⇒x³ − 2x² + 4x + 2x² − 4x + 8

⇒x³ + 8

∴ The degree of the polynomial x³ + 8 is 3. As the degree means The highest or greatest degree of a variable in a polynomial.

Answer 2

Answer:

the degree of the polynomial is 3 .

Explanation:

(x + 2)(x² - 2x + 4).

x³ - 2x² + 4x + 2x² - 4x+8

x³+8

the highest power of the polynomial is degree of the polynomial . so,

the answer is 3
