Question

Find the degree of polynomial (x²+9)(5-x²)

Answer 1

(x²+9)(5-x²)
=>x²(5-x²)+9(5-x²)
=>5x²-x⁴+45-9x²
so,the degree is 4 bcoz the highest power of x is 4

Here is ur answer :

First we have to find its product

➡️(x²+9)(5-x²)

➡️x² ( 5 - x² ) + 9 ( 5 - x² )

➡️ 5x² - x⁴ + 45 - 9x²

➡️ - x⁴ - 4x² + 45

Degree of the polynomial = 4
