Solutions to a squared equation that aren't direct solutions of the original equation are called extraneous solutions.
What is an extraneous solution?
In Mathematics, an extraneous solution can be defined as a type of solution (root) to a squared equation or transformed equation that isn't a direct solution (root) of the original equation.
This ultimately implies that, extraneous solutions are numerical values that are obtained when we solve equations that aren't solutions to the original equation.

Convert the following complex number into its polar representation -4i
The expression which represent the polar form of complex number -4i when converted into the polar form is 4(cos π+ isin π)
What is complex number?A complex number is the combination of real and imaginary number. In a complex number, real part and imaginary part of number is written together. For example,
a+bi
Here, (a) is the real part while (b) is the imaginary part.
The complex number which need to convert into its polar representation is,
n=-4i
It can be rewritten as,
n=0-4i
The radius r of the polar form is,
r²=0²+(-4)²
r²=0+16
r=4
The value of cos theta is,
tan θ=0/-4
θ=tan⁻¹(0)
θ=π
Thus, the polar form is,
z=rcos θ+(r sin θ)i
z=-4(cos π+ isin π)
Thus, the expression which represent the polar form of complex number -4i when converted into the polar form is 4(cos π+ isin π)

If r is a commutative ring, show that the characteristic of r[x] is the same as the characteristic of r.
If R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.
What is a commutative ring?In ring theory, a commutative ring can be defined as a ring in which the multiplication operation is considered to be commutative in nature.
Let R represent a commutative ring with characteristic K.
Therefore, we have: Kr = 0∀r ∈ R.
Assuming f(x) ∈ R(x)
Then, f(x) would be given by: [tex]a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0=0[/tex]
Also, in some instances ai ∈ R and n ∈ N.
Finally, we would have:
[tex]Kf(x) = K(a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0)\\\\Kf(x) = Ka_n x^n + Ka_{n-1} x^{n-1} +.......+ Ka_1 x^1 +Ka_0\\\\Kf(x) = 0\times x^n + 0\times x +.......+ 0[/tex]
Kf(x) = 0.
Therefore, we can infer and logically deduce that if R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.
