Question

(x² - 2) (9x² - 2x + 5)​

Answer 1

Answer:

Step-by-step explanation:

(x² - 2) (9x² - 2x + 5)​

( 9x^4 - 2x^3 + 5x^2 - 18x^2 + 4x - 10)

(9x^4 - 2x^3 - 13x^2 + 4x - 10)

Answer 2

Solution

$\bf= (x {}^{2} - x)(9x {}^{2} - 2x + 5) \\ \bf = (9x {}^{4}) - 2x {}^{3} + 5x {}^{2} - 18 {}^{2} + 4x - 10) \\ \bf = (9x {}^{4} - 2x {}^{3} - 13 {}^{2} + 4x - 10)$
