Perform the operation indicated, then place the answer in the proper location on the grid. Write your answer in descending power
VikaD [51]

Answer:

<h3>The answer after performing the indicated operation is in descending powers of x is 5x^2-7x+15</h3>

Step-by-step explanation:

Given expression is (6x^2-4x+11)+(4-x^2-3x)

<h3>To perform the operation indicated, then place the answer in the proper location on the grid and also Write answer in descending powers of x:</h3>

Now solve the given expression as below ( that is perform the operation indicated)

(6x^2-4x+11)+(4-x^2-3x)

=6x^2-4x+11+4-x^2-3x

Adding the like terms we get

=5x^2-7x+15

(6x^2-4x+11)+(4-x^2-3x)=5x^2-7x+15

<h3>The answer after performing the indicated operation is in descending powers of x is 5x^2-7x+15</h3>

Find a polynomial equation that has roots of -2 and double root 3
lbvjy [14]

Answer:

x³ + 2x² -3x +6

Step-by-step explanation:

We need to find the polynomial whose roots are ,

  • -2 , √3 and √3.

Say of we have zeroes as , α , β and γ , then the polynomial is ,

=> p(x) = k[ (x - α ) ( x - β) ( x - γ) ]

  • where k is constant. Substituting the respective values , we have ,

=> p(x) = k [ ( x - (-2)) ( x - √3) ( x -√3)]

=> p(x) = k[ (x+2)(x² - 3)]

=> p(x) = k[ x(x² - 3) + 2(x² - 3) ]

=> p(x) = k[ x³ - 3x + 2x² - 6 ]

=> p(x) = k[ x³ + 2x² - 3x - 6 ]

<h3><u>Hence </u><u>the</u><u> </u><u>cubic </u><u>polynomial</u><u> is</u><u> </u><u>x³</u><u> </u><u>+</u><u> </u><u>2</u><u>x</u><u>²</u><u> </u><u>-</u><u> </u><u>3x</u><u> </u><u>+</u><u> </u><u>6</u><u> </u><u>.</u></h3>

Vanessa was baking cookies. Each batch of cookies made 3 dozen. If Vanessa uses 6 cups of flour total and each batch requires 1
erastovalidia [21]
Each batch gives you 3 dozen and you need 1 1/2 cups for each batch of cookies

she uses 6 cups in total, so divide 6 by 1 1/2 to get the number of batches

6 ÷ 1 1/2 = 4 batches

so 4 batches × 3 dozen cookies = 12 dozen cookies
