Question

Find the product of the complex number and it's conjugate; 7-6t

Answer 1

hint:

(a+bi)*(a-bi) = a^2 + b^2

Answer 2

7-6t doesn't look very complex per se

Answer 3

I'm sorry I really don't understand

Answer 4

the number is 7-6i right?

Answer 5

Yes, but how do I get a product from that

Answer 6

the conjugate is 7+6i

Answer 7

multiply the two numbers using the rule I posted above

Answer 8

or you can expand it out the long way

Answer 9

How do I get a product withput an = sign?

Answer 10

in this case, a = 7 and b = 6

Answer 11

so...

(a+bi)*(a-bi) = a^2 + b^2

(7+6i)*(7-6i) = 7^2 + 6^2

(7+6i)*(7-6i) = ???

Answer 12
