Answer:
Third zero is -1.
Step-by-step explanation:
consider the given polynomial is
It is given that -1 and -3 are two zeroes, therefore (x+1) and (x+3) are two factors of given polynomial.
The given polynomial can be rewritten as
Now, splitting the middle term, we get
Here, power of (x+1) is 2. It means the multiplicity of zero -1 is 2.
So, three zeroes are -1, -1 and -3.
Therefore the third zero is -1.
Answer:
x = 30
Step-by-step explanation:
Since you're dividing x by 3, multiply each side by 3. The 3 on the left side gets cancelled out, leaving you with x = 30.
I hope this helped.
4(7x−3)−6=6−4(3x−7)
Distributive property
28x - 12 - 6 = 6 - 12x + 28
28x - 18 = -12x + 34
28x + 12x = 34 + 18
40x = 52
x = 52/40
x = 13/10
or
x = 1 3/10 (mixed number: 1 and 3/10)
Answer:
+3
Step-by-step explanation:
(-m)^(-3) = -m^3, since (-1)^-3 = 1 / (-1).
If m = 2 then we have -2^(-3), or -1 / [2^3]), or -1/8.
Finally, if n = -24, the original expression becomes
(-1/8)(-24) = +3
Second problem: Only the first expression simplifies to a negative result.
