2x^4 + x^3 − 8x^2 − 4x
= x ∙ (2x^3 + x^2 − 8x − 4)
= x ∙ (x^2 ∙ (2x + 1) − 4 ∙ (2x + 1))
= x ∙ (x^2 − 4) ∙ (2x + 1)
= x ∙ (x − 2) ∙ (x + 2) ∙ (2x + 1)
Thus the roots are:
x ∙ (x − 2) ∙ (x + 2) ∙ (2x + 1) = 0
⇒ [x = 0] or [x − 2 = 0] or [x + 2 = 0] or [2x + 1 = 0]
⇒ [x = 0] or [x = 2] or [x = −2] or [x = − 1/2]
Answer: Divide each term in 3 a ≥ − 6 by 3 . 3 a 3 ≥ − 6 3 Cancel the common factor of 3 . Tap for more steps... a ≥ − 6 3 Divide − 6 by 3 . a ≥ − 2 The result can be shown in multiple forms. Inequality Form: a ≥ − 2 Interval Notation: [ − 2 , ∞ )
Hey there!
36y - 12
FIRST LOOK AT THE GCF (Greatest Common Factor)
36y: 1, 2, 3, 4, 6, 9, 12, 18, 36, and y
12: 1, 2, 3, 4, 6, and 12
GCF: 12
So, 12 would most likely be number before you make your parentheses
12(?y - 1)
The numbers in your original equation both share 3 & -1
So, therefore the factor form of your equation should be: 12(3y - 1)
Answer: 12(3y - 1)
Good luck on your assignment & enjoy your day!

Answer:
16.4 m to the nearest tenth.
Step-by-step explanation:
After the first bounce it rises to a height of 50*0.8 = 40 m.
After the next bounce it rises to 50*(0.8)^2 = 32 m
So after the 5th bounce it rises to 50(0.8)^5 = 16.4 m. (answer).
He lived 9 months in Portugal and 5 months in Brazil. This is because 130*9 + 150*5 = 1920.
