Answer:
<u>f(x) = = (x + √2 i) (x - √2 i) (x - 2 ) (x + 1)</u>
Step-by-step explanation:
The given function is f(x) = x⁴ - x³ -2x -4
factor the polynomial function
f(x) = x⁴ - x³ -2x -4 = (x⁴ - 4) - (x³ + 2x ) ⇒ take (-) as a common from (- x³ -2x)
= (x² + 2 ) (x² - 2) - x (x² + 2) ⇒ take (x² + 2) as a common
= (x² + 2 ) ( x² - x - 2)
= (x + √2 i) (x - √2 i) (x -2 ) ( x+1)
Notes: (x⁴ - 4) = (x² + 2 ) (x² - 2)
(x² + 2)= (x + √2 i) (x - √2 i)
( x² - x - 2) = (x -2 ) ( x+1)

Answer:
the GCF is 3 so 2b - 3k
Step-by-step explanation:
Answer:
13 bowls
Step-by-step explanation:
To figure out how many bowls of nuts she can make, we divide how many cups of nuts she has by how many cups of nuts in a bowl
3 3/8 ÷ 1/4
Lets change 3 3/8 into an improper fraction
3 3/8 = (8*3 +3)/8 = 27/8
27/8 ÷ 1/4
Copy dot flip
27 /8 * 4/1
27/2
2 goes into 27 13 times with 1 left over
13 1/2
She will have 13 full bowls of nuts
Answer:
1.5
Step-by-step explanation:
Vertical angles are congruent so:
7x=8x-12
Subtract 7x from both sides:
0=8x-12
Add 12 to both sides:
8x=12
Divide both sides by 8:
x=1.5 or
x= 3/2
