12. (2v^3 - v + 8) + (-v^3 + v - 3)<br><br> 14. (4h^3 + 3h + 1) - (-5h^3 + 6h - 2)
Lana71 [14]
12. On addition, you can just combine like terms.
2v^3+(-v^3)=v^3
-v+v cancels each other out
8+(-3)=5
So you have v^3+5

14 On subtraction, you have to remember to distribute the negative sign so after you do that you have:
4h^3+3h+1+5h^3-6h+2
Then you can combine like terms
4h^3+5h^3=9h^3
3h-6h=-3h
1+2=3
So you end up with:
9h^3-3h+3

Hope that helps and feel free to ask any questions.

Find the value of x so that the function has the given value. <br> q(x)=12x−3; q(x)=−4
Anna [14]

Answer:

-  \frac{1}{ 12}

Step-by-step explanation:

since q(x)=-4

substitute

hence

-4=12x-3

take -3 to the other side where it becomes positive

therefore

-1=12x

divide by 12

you will get the above answer

Use synthetic division to show that x is a solution of the third-degree polynomial equation, and use the result to factor the po
Flura [38]

You didn't state the value of x which you want to be shown to be a solution of the given polynomial

3x³ - 19x² + 30x - 8 = 0.

This polynomial of degree three obviously, has three solutions, and 2 is one of the solutions.

I will assume 2 to be the value of x you didn't state, and work with it. But the number is not 2, then it must be one of the remaining two solutions which would follow the same procedure that I will show here.

Answer:

The solutions to the equation

3x³ - 19x² + 30x - 8 = 0

are x = (2, 4, 1/3).

Step-by-step explanation:

Given the polynomial

3x³ - 19x² + 30x - 8 = 0

We need to show that x = 2 is a solution using synthetic division. If x = 2 is a solution, the remainder obtained from the synthetic division

(3x³ - 19x² + 30x - 8) ÷ (x - 2)

is zero.

SYNTHETIC DIVISION

2 | 3 ..... -19 ..... 30 ..... -8

................. 6 .... -26 ...... 8

.... 3........ -13 ........4 .......0->Remainder

Explanation:

The first row:

2 is from the divisor (x - 2). Always take the opposite of what you have. If the divisor is (x + 5), take -5.

(3, -19, 30, -8) are the coefficients of the divisor, the polynomial of degree three.

The coefficient of x³ is dropped to the third column.

2 is multiplied by 3 in the third column to obtain 6 in the second column.

6 is added to -19 to obtain -13.

Again, multiply 2 by -13 in the third column, to obtain -26 in the second column. Add this to 30 to obtain 4

Repeat this process, 2 × 4 = 8

8 + (-8) = 0.

Since 0 is the remainder, x = 2 is a solution to the polynomial.

The remaining factors can be found from the resulting polynomial of degree two whose coefficients were obtained from the synthetic division.

The coefficients of the polynomial are: 3, -13, 4

So, the polynomial is: 3x² - 13x + 4.

The zeros of this polynomial are the remaining factors we are looking for.

We solve

3x² - 13x + 4 = 0

(x - 4)(3x - 1) = 0

x - 4 = 0

=> x = 4

3x - 1 = 0

=> x = 1/3

x = 4, 1/3

The solutions to the equation are x = (2, 4, 1/3).
