Move 9 over to the other side so your equation looks like this:
9n = 9 - 9
Then simplify
9n = 0
n = 0

Step 1: Move all terms not containing <span>n</span> to the right side of the equation.
Since <span>9</span> does not contain the variable to solve for, move it to the right side of the equation by subtracting <span>9</span> from both sides.

<span><span>9n = −9+9
</span><span>9n=-9+9
</span></span>Add <span><span>−9</span></span> and <span>9</span> to get <span>0</span>.
<span><span>9n=0</span><span>

</span></span>Step 2: Divide each term by <span>9</span> and simplify.
Divide each term in <span><span>9n = 0 by 9
</span><span>9n=0</span></span> by <span>9</span>.
<span><span><span><span>9n/</span>9</span>=<span>0/9

</span></span></span>Step 3: Reduce the expression by canceling the common factors.
<span><span>n=<span>0/9
</span></span></span>Divide <span>0</span> by <span>9</span> to get <span>0</span>.
<span>n=<span>0</span></span>

Is (x-1) a factor of 2x3 - 15x2 + 22x + 15
Advocard [28]

Answer:

Step-by-step explanation:

If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?

f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15

f(1) = 2 - 15 + 22 + 15

f(1)= 24.

No the result is not zero. So x - 1 is not a factor.

However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.

The numbers that do make this zero are -0.5, 3, 5

Which mean that the factors are (2x+1)(x-3)(x - 5)
