Answer:

-9s^2 + 4s -2

Step-by-step explanation:

The distributive says that:

a \cdot(b+c) = a\cdot b+ a\cdot c

Simplify:

(-6s^2 + 12s - 8) - (3s^2 + 8s - 6)

Apply the distributive property we have;

-6s^2 + 12s - 8- 3s^2-8s+6

Combine like terms;

-9s^2 + 4s -2

Therefore, the result we get, -9s^2 + 4s -2

6. Consider the polynomial p(x) = x^2 + kr^2 +x+6. Find a value of k so that x+1 is a factor of P. Find all the zeros of P.​
Nikitich [7]

If <em>x</em> + 1 is a factor of <em>p(x)</em> = <em>x</em>³ + <em>k</em> <em>x</em>² + <em>x</em> + 6, then by the remainder theorem, we have

<em>p</em> (-1) = (-1)³ + <em>k</em> (-1)² + (-1) + 6 = 0   →   <em>k</em> = -4

So we have

<em>p(x)</em> = <em>x</em>³ - 4<em>x</em>² + <em>x</em> + 6

Dividing <em>p(x)</em> by <em>x</em> + 1 (using whatever method you prefer) gives

<em>p(x)</em> / (<em>x</em> + 1) = <em>x</em>² - 5<em>x</em> + 6

Synthetic division, for instance, might go like this:

-1   |   1    -4     1     6

...   |         -1    5    -6

----------------------------

...   |   1    -5    6     0

Next, we have

<em>x</em>² - 5<em>x</em> + 6 = (<em>x</em> - 3) (<em>x</em> - 2)

so that, in addition to <em>x</em> = -1, the other two zeros of <em>p(x)</em> are <em>x</em> = 3 and <em>x</em> = 2

Please Help- <br> K + ⅓ = 5 ⅛ | K = ?<br> Show Your Reasoning.
blondinia [14]

Answer:

4\frac{19}{24}

Step-by-step explanation:

I hope I did this right:

So first thing to do is set up the equation.

K + \frac{1}{3} = 5\frac{1}{8}

Next thing to to is subtract 1/3 from both sides to get:

K = 5\frac{1}{8} - \frac{1}{3}

Next up, you will multiply each of the fractions by the opposing value

(multiply 1/8 by 3 and 1/3 by 8)

K = 5\frac{3}{24}-\frac{8}{24}

Alright almost done, by multiplying 24 by 5 you get 120, that will go in the numerator to make the math a lot easier.

K = \frac{123}{24}-\frac{8}{24}

Finally, you subtract 123 over 24 by 8 over 24.

K = \frac{123}{24} - \frac{8}{24} = \frac{115}{24}

Then just simplfy the 115/24 to get

4\frac{19}{24}
