What is the result of dividing 2x^3+6x^2+6x+2 by x+1 ? , will give 5 rating

The result we would get when   is divided by x + 1 is:

B.

An easy way is to multiply the x + 1 by each of the polynomials in each option given to determine which will result to

First Option:

Second option:

We can see that multiplying x + 1 by the second option, , will give us  .

If  we multiply the rest options by x + 1, we won't get  .

Therefore, the result we would get when   is divided by x + 1 is:

B.

2x² + 4x + 2

using long division to obtain the quotient

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
