Question

4. What is the result of 3^2x-5x+1 from 8x^2 -2x-9?

a. 5x2 +3x - 10
b. -5x2-3x -10
C. 5x2 -7X-8
d. 5x2 -7x +8

Answer 1

a) 5 x² + 3 x -10

Explanation:

Explanation:-

Given polynomials

3 x² - 5 x + 1 and 8 x² - 2 x -9

Given that

3 x² - 5 x + 1 From 8 x² - 2 x -9

⇒ 8 x² - 2 x -9 - ( 3 x² - 5 x + 1 )

= 8 x² - 2 x -9 - 3 x² + 5 x - 1

= 5 x² + 3 x -10
