Difference of Squares gives which complex factors for the expression +3?

Mathematics
1 answer:
Oduvanchick [21]2 years ago
3 0

The difference of squares is:

(x+i√3)(x-i√3)

So the correct option is the last one, D.

<h3>Which expression gives x^2 + 3?</h3>

For a complex number:

Z = a + b*i

We define the complex conjugate of Z as:

Z' = a - b*i

Such that the product between the complex number and its complex conjugate gives:

Z*Z' = a^2 + b^2

Now, of you look at option D, you can see we have the product of a number and its conjugate, then we can write the product and use the above rule to get:

(x + i\sqrt{3} )*(x - i\sqrt{3} ) = x^2 + (\sqrt{3} )^2 = x^2 + 3

Which is what we wanted to get, so that is the correct option.

The plans were made too hastily, without enough
Talja [164]

The answer is (C). By referring to the plural word "plans" with a plural pronoun ("them"), it avoids the error of the original.

The reason was given for Wrong Answer A: Choice (A) contains an agreement mistake. It is incorrect to use the singular pronoun "it" to refer to the plural noun "plans."

The reason given for Wrong Answer B: In option (B), the alteration is done incorrectly. Hasty should be changed to "hastily" to modify the verb "manufactured."

Justification for Wrong Answer D: Improper alteration is involved in Option (D). Hasty should be changed to "hastily" to modify the verb "manufactured."

Justification for Wrong Answer E: Choice (E) has an agreement mistake. It is incorrect to use the singular pronoun "it" to refer to the plural noun "plans."
