Match the polynomial expression on the left with the simplified version on the right.
Vitek1552 [10]

Given the following question:

First expression:

\begin{gathered} \frac{12x^3-14x^2+16x-8}{3x-2} \\ \text{ Factor the expression:} \\ 12x^3-14x^2+16x-8=2(6x^3-7x^2+8x-4) \\ \frac{2\left(6x^3-7x^2+8x-4\right)}{3x-2} \\ \text{ Factor:} \\ 2\left(6x^3-7x^2+8x-4\right)=(3x-2)(2x^2-x+2) \\ =(3x-2)(2x^2-x+2)=2\left(3x-2\right)\left(2x^2-x+2\right) \\ \frac{2\left(3x-2\right)\left(2x^2-x+2\right)}{3x-2} \\ \text{ Cancel the common factor:} \\ -(3x-2) \\ 4x^2-2x+4 \end{gathered}

Solve for x: |2x + 12| = 18
erastova [34]
|2x + 12| = 18

First, break down the problem into 2 equations . / 2x + 12 = 18 and -(2x + 12) = 18
Second, solve the first equation. / 2x + 12 = 18
Subtract 12 from both sides. / 2x = 18 - 12
Subtract 18 - 16. / 2x = 6
Divide both sides by 2. / x =  \frac{6}{2}
Simplify. / x = 3
Third, solve the second equation. / -(2x + 12) = 18
Simplify your brackets. / -2x - 12 = 18
Add 12 to both sides. / -2x = 18 + 12
Add 18 + 12. / -2x = 30
Divide both sides by -2. / x =  \frac{30}{-2}
Simplify. / x =  -\frac{30}{2}
Simplify. / x = -15
Fourth, collect the solutions. / x = -15,3

Answer: x = -15, 3

Factor and simplify: 4a^2c^2(a^2-b^2+c^2)^2
Dvinal [7]
4a^2c^2(a^2-b^2+c^2)^2 First, solve the exponent around the quantity. Being that it's a power of a power, you would multiply all the exponents inside the parentheses by two. So, after that, it would be: 4a^2c^2(a^4-b^4+c^4) Then, you would multiply what's outside the parentheses with every term within the parentheses: (4a^6c^2)-(4a^2c^2b^4)+(4a^2c^6) Now, you think you can take it from here, or do you need me to keep going?

How do you write 26.2 as a mixed number in simplest form
Arte-miy333 [17]
To write 26.2 as a mixed number in the simplest form, do the following:
26.2 = 26 + 0.2
         = 26 + 2/10

Note that 
\frac{2}{10}= \frac{2 \times 1}{2 \times 5}  = \frac{1}{5}

Therefore
26.2 = 26 \, \frac{1}{5}  \\

Answer:  26 \,  \frac{1}{5}
