Answer:
x^2 -2x +5
Step-by-step explanation:
x^2 -2x +5
----------------------------------------------------------
2x + 5 / 2x^3 + x^2 + 0x + 25
-(2x^3 + 5x^2)
----------------------------
-4x^2 + 0x
-( -4x^2 - 10x )
-----------------------------------------
10x + 25
-(10x + 25)
---------------------------
0
The desired quotient is x^2 -2x +5
1. -10v(v^3 + 6v^2 + 7)
2. 4m^2(3m^3 + 9m + 10)
3. 10(n^2 + 5n - 8)
4. 42^3= 70488/18= 4166
42^2= 1764/18= 98
-18(x^4 + 4166 - 98)
Answer:
4, 12, 8, 10
Step-by-step explanation:
Ratio:
Hydrogen : Oxygen
2:1
