Aleksandr-060686 [28]4 years ago
3 0

Answer:

28 , 28, -14

Step-by-step explanation:

x2+6x+8=0

4(2)+6(2)+8=0

8+12+8=0

28=0

x2+6x+8=0

-4(2)+6(2)+8=0

8+12+8=0

28=0

x2+6x+8=0

-8(2)+6(-1)+8=0

-16-6+8

-14=0

Wen is factoring the polynomial, which has four terms. 6x3 – 12x2 7x – 14 6x2 (x – 2) 7(x – 2) Which is the completely factored
-Dominant- [34]

The completely factored form of the Wen's polynomial, which has the four terms initial, is,

(6x^2+7)(x-2)

<h3>What is the factor of polynomial?</h3>

The factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.

Wen is factoring the polynomial, which has four terms.

6x^3 - 12x^2+ 7x - 14 '

Take out the greatest common factor from the equation and make separate groups as,

6x^2(x - 2)+ 7(x - 2)\\(x-2)(6x^2+7)

Rearrange the above equation as,

(6x^2+7)(x-2)

Thus, the completely factored form of the Wen's polynomial, which has the four terms initial, is,

(6x^2+7)(x-2)

A chemistry teacher needs to mix a 20% salt solution with a 80% salt solution to make 25 qt of a 44% salt solution. How many qua
NNADVOKAT [17]
Let there be x quarts of the 20% salt solution, and (25 - x) quarts of the 80% salt solution.
Then the total amount of salt in the 20% portion would be 0.2x, while that from the 80% portion would be (0.8)(25 - x). This would have to total up to (0.44)(25) in the final solution, so the equation is:
0.2x + 0.8(25 - x) = (0.44)(25)
-0.6x + 20 = 11
x = 15 quarts of the 20% salt solution
25 - x = 10 quarts of the 80% salt solution

What is 2x-64&lt;108 If you answer this I will give you a total of 23 points!
alexandr1967 [171]

Answer:

2x-64<108

One solution was found :

x < 86

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

2*x-64-(108)<0

Step by step solution :

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

2x - 172 = 2 • (x - 86)

Equation at the end of step 1 :

Step 2 :

2.1 Divide both sides by 2

Solve Basic Inequality :

2.2 Add 86 to both sides

x < 86
