X^4-11x^2+18=0 factor
Ede4ka [16]

Answer:

(x² - 9)(x² - 2) = 0

x = 3 or √2

Step-by-step explanation:

To factor a polynomial, you need to find two expression that when multiplied together using FOIL (first, outside, inside, last) will produce the polynomial.  In this case the polynomial x^{4}-11x^{2}+18=0 can be factored into:

(x² - 9)(x² - 2) = 0

Setting each of these expressions equal to '0':

x² - 9 = 0 or x² = 9 so √x² = √9 or x = 3

x² - 2 = 0 or x² = 2 so √x² = √2 or x = √2

If n is a positive integer and r is the remainder when (n – 1)(n + 1) is divided by 24, what is the value of r?
11Alexandr11 [23.1K]

(1) n is not divisible by 2 --> pick two odd numbers: let's say 1 and 3 --> if , then and as zero is divisible by 24 (zero is divisible by any integer except zero itself) so remainder is 0 but if , then and 8 divided by 24 yields remainder of 8. Two different answers, hence not sufficient.

(2) n is not divisible by 3 --> pick two numbers which are not divisible by 3: let's say 1 and 2 --> if , then , so remainder is 0 but if , then and 3 divided by 24 yields remainder of 3. Two different answers, hence not sufficient.

(1)+(2) Let's check for several numbers which are not divisible by 2 or 3:

--> --> remainder 0;

--> --> remainder 0;

--> --> remainder 0;

--> --> remainder 0.

Well it seems that all appropriate numbers will give remainder of 0.
