Princess poly says that the product of (74x+94i) and (74x−94i) is (4916x2+8116). which statement is true regarding her product? her product is not correct. the expression (74x+94i)(74x−94i) can be written as the difference of squares (74x)2−(94i)2, which is equal to 4916x2−8116. her product is not correct. the expression (74x+94i)(74x−94i) can be written as the difference of squares (74x)2−(32i)2, which is equal to 4916x2−94. her product is not correct. the expression (74x+94i)(74x−94i) can written as the difference of squares (74x)2−(32i)2, which is equal to 4916x2−94. her product is correct. the expression (74x+94i)(74x−94i) can be written as the difference of squares (74x)2−(94i)2, which is equal to 4916x2+8116.

As you must know that (a + bi) and (a-bi) are complex numbers,each being conjugate of each other.

The meaning of conjugate is change the sign of the number preceding imaginary part.

In a+bi ,bi being the imaginary part .  It has positive sign before it .so just change the sign to -(negative) .So a-bi is the conjugate of a+bi. Similarly a+bi is the conjugate of a-bi.

Now com to the product of two complex number which are conjugate of each other.

(a+bi)(a-bi)=

                 =

So product of (74 x +94 i) and (74 x-94 i) which are conjugate of each other , their product will be

=

The expression (74x+94i)(74x−94i) can be written as the difference of squares (74x)2−(94i)2, which is equal to 4916x2+8116.

This statement is true for Princess Poly Regarding her product of (74x+94i) and (74x−94i).

Solution:

(74x + 94i) x (74x - 94i)

can be written as (74x)² - (94i)²

which is equal to 5476x² + 8836

Given:

(74x + 94i) x (74x - 94i)

Formula Used:

Using the fact that

Explanation:

Given the expression

Note:

The calculation suggests that 5476x² + 8836 is the final answer. Could 4916x²-8116 be a typo? Please update/confirm and I would be happy to provide any follow-ups required!

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
