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)
I’m not sure if your asking for the solution, but Hope this helps!
Answer:
x is less than or equal to 9
which is x ≤ 9
Step-by-step explanation:
ABOUT SLOPE INTERCEPT FORM:
- y = mx + b
- m represents the slope
- b represents the y-intercept
You have to get y by itself:
5x + 8y = 16
-5x -5x
<u>8y = -5x + 15</u>
8 8
y = -5/8x + 15/8
OR
I you wants to simplify 15/8, it's this:
y = -5/8x +1.875
HI!!! Really really sorry if I'm incorrect...
