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

-54 is not a perfect cube; thus, the answer contains cube roots. Because this site doesn't allow us to insert images in answers, we'll let C(x) represent "the cube root of X" such that C(8) = 2, etc. The answer, then, is 3 * C(-2).

How do you find the cube root of a negative number?

If the negative number is "-a", then you can say the cube root is "-(cube root of a)" Because if you cube a negative number, you get a negative number. So if you cube root a negative number, you get a negative number. Ex) cube root of -8 = -2 Because (-2)^3 = -8 But if you want to find the complex cube roots, you can make an equation: "x^3=-a" or "x^3+a=0" We know one of the roots is "-(cube root of a)" so you can factor the equation by (x+(cube root of a)) And then you use the quadratic formula for the quadratic equation you're left with. Ex) x^3=-8 or x^3+8=0 Since -2 is a root, factor it by (x+2) x^3+8=(x+2)(x^2-2x+4) Using the quadratic formula, you get "1+i√3" and "1-i√3" Therefore the three cube roots of -8 is <"-2", "1+i√3", "1-i√3">

They are not, other that the fact that any perfect square is a non-negative and so is also a cube root of some non-negative integer (usually much larger). But -2 is a cube root (of -8), while -8 is not a perfect square.

What is Cube Root of A Number?

it is the number which when multiplied by itself three times give you the original number. For example, the cube root of 8 is 2 (2x2x2 = 8) This works for negative numbers as well Forexample, the cube root of -27 is -3 [(-3)x(-3)x(-3) = -27]


Why can you cube root a negative number but you cannot square root a negative number?

When two negative or two positive numbers are multiplied together, they always result in a positive number; and when a positive and a negative number are multiplied together, they will always result in a negative number. Thus, you cannot square root a negative number because there are no real numbers that, when squared, would result in a negative number. For example: (-2)(-2) = 4 (2)(2) = 4 √4 = +/- 2 √(-4) = ? No real number, when squared, is a negative! Does not exist! The cube of a number is different, because you are multiplying three numbers together instead of just two. As a result, you can get a negative or a positive number. For example: (-2)(-2)(-2) = -8r (2)(2)(2) = 8 3√8 = 2 3√(-8) = -2


What rational exponent represents a cube root squared?
