State the degree of the polynomial -x4

emmainna [20.7K]

-x^4

The degree is the exponent, and he amount of degrees there are depends on the amount of degrees in each monomial.

In this case, there is only one monomial, with it's degree as 4

4 is your answer

hope this helps

Resolve in factors. I) x⁴+x²+1

masha68 [24]

Answer:

let a = x² (a ≥ 0), we have the equation:

a² + a + 1 = 0

⇔ a² + 2.1/2.a + 1/4 + 3/4 = 0

⇔ (a + 1/2)² = -3/4 (unreasonable)

=> no solutions

Ahmed is solving the following equation for xxx.

Dennis_Churaev [7]

Answer:

Step-by-step explanation:

An extraneous solution is a root of a transformed equation which is not a root of the original equation because it was not included in the domain of the original equation.

Ahmed is solving $2\sqrt[3]{x-7}+11=3$ for x.

His steps were:

$\begin{aligned}2\sqrt[3]{x-7}&=-8\\ \sqrt[3]{x-7}&=-4\\ \left(\sqrt[3]{x-7}\right)^3&=(-4)^3\\ x-7&=-64 \end{aligned}$

Since cube roots <u>do not give two solutions when solved</u>, it is <u>not necessary </u>to check his answers for extraneous solutions.
