3x^3+x+2x^3-4x^2+14y-2(y+x) simplify this polynomial

Stels [109]

3x³ + x + 2x³ - 4x² - 2(y + x)
3x³ + 2x³ - 4x² + x - 2(y) - 2(x)
5x³ - 4x² + x - 2y - 2x
5x³ - 4x² + x - 2x - 2y
5x³ - 4x² - x - 2y

Simplify fully: X^2+3x-4/ 2x^2-5x+3

sweet-ann [11.9K]

Answer:

(-x - 3) • (x - 1)

Step-by-step explanation:

Step 1 :

2

Simplify —

1

Equation at the end of step 1 :

((((x2)+3x)-(2•x2))-5x)+3

Step 2 :

Equation at the end of step 2 :

((((x2) + 3x) - 2x2) - 5x) + 3

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

-x2 - 2x + 3 = -1 • (x2 + 2x - 3)

Trying to factor by splitting the middle term

4.2 Factoring x2 + 2x - 3

The first term is, x2 its coefficient is 1 .

The middle term is, +2x its coefficient is 2 .

The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 1 • -3 = -3

Step-2 : Find two factors of -3 whose sum equals the coefficient of the middle term, which is 2 .

-3 + 1 = -2

-1 + 3 = 2 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -1 and 3

x2 - 1x + 3x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x-1)

Add up the last 2 terms, pulling out common factors :

3 • (x-1)

Step-5 : Add up the four terms of step 4 :

(x+3) • (x-1)

Which is the desired factorization

Final result :

(-x - 3) • (x - 1)

Create a real life representation of the following multiplication problem <br> 24(1/3) =8

dlinn [17]

Answer:

Amanda bought 24 pounds of turkey for the eve of Christmas. She decided to cook one third of the turkey for the guests coming over lunch. So she will cook one third of 24 pounds that is 8 pounds of turkey for the lunch.

Step-by-step explanation:

We have been given a multiplication problem $24(\frac{1}{3} )=8$ .

<em>Basically it says one third of 24 is 8. </em>

So a real life representation of the following multiplication problem can be represented as follows:

Amanda bought 24 pounds of turkey for the eve of Christmas. She decided to cook one third of the turkey for the guests coming over lunch. So she will cook one third of 24 pounds that is 8 pounds of turkey for the lunch.
