What is the sum of the given polynomials in standard form? (x2 – 3x) (–2x2 5x – 3) –3x2 8x – 3 –x2 – 2x – 3 3x2 – 8x 3 –x2 2x – 3

Option (d) is correct.

Step-by-step explanation:

Given : Polynomials

We have to find the sum of given polynomials.

Consider the given polynomials  

Sum is given by

Expand by removing brackets , we have

Apply plus minus sign , we get,

Adding like terms,

LIKE TERMS are terms having same variable with same degree, we get,

Thus, Option (d) is correct.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

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

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
