Suppose 12 is the GM of 16 and x

then 12 = sqrt(16*x)

squaring both sides: 144 = 16*x

so that x = 9

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the geometric mean of 12 and 6?

The geometric mean of the set { 12, 16 } is the square root of 192, or approximately 13.856.To find a geometric mean from a set of numbers, you find the product of the members of the set, and then take the nth root of that product, where n equals the count of the number of members in the set.Given the set { 12, 16 } our count is 2. Therefore, we will be taking the 2nd root (or "square root.")SQRT( 12 * 16 )SQRT( 192 ) or approximately 13.856

Why do you think 16 is called a square number while 7 and 12 are not?

16 is the square of 4 (by that I mean that 4x4 = 16). 7 and 12 are not squares because they do not have a number that, when multiplied by itself, gives you 7 or 12.

No. It is 12Here is why:The geometric mean of 3 and 48 is the square root of 3x38=144So it is the square root of 144 which is 12.In general, the geometric mean of the numbers a1 a2 ....an is the nth root of the product of the ai from i=1 to i=n


Two geometric means between 2 and 54?

Look 2 and 8, their geometric mean is square root of 16 which is 4 and between 2 and 54. 9 and 4 have a geometric mean of 6 which is also between 2 and 54. Is this what you mean? Pun intended... The geometric mean of 2 and 54 is square root of 108.
