Answer:

(x+1) (x^2+1)

Step-by-step explanation:

x^3+x^2+x+1

Factor by grouping

x^3+x^2 +x+1

Factor out x^2 from the first group and 1 from the second group

x^2( x+1) + 1( x+1)

Factor out (x+1)

(x+1) (x^2+1)

Add the like terms and it would be x6+1 this is because if x is being multiplied by 3 and then the other x is multiplied by 2 then we can just add the numbers and get 5 and x by itself is also x1 because 1 times whatever number will always just be the other number so with 3+2+1 we have 6x and then the other 1 would just be +1

Find geometric mean of 4 and 12?

Law Incorporation [45]

The geometric mean is different than algebraic mean - algebraic is adding up all the numbers and dividing it by the number of numbers, but geometric is multiplying them and getting the root of the product of all the numbers. For example, if there were 10 numbers, we would have the 10th root of the product of all the numbers or the product to the power of 1/10.

Since there are 2 numbers, we simply have the square root - $\sqrt{4*12} =2* \sqrt{12} = 4* \sqrt{3}$ due to that 2²=4, so we can divide what is in the square root by that and take the 2 out.
