Question

(2+3i) (2-3i) plzzzz slove this equation and answer me ​

Answer 1

it is not an equation ...this an expression...

I can only .... simplify this okk

$(2 +3 i)(2 - 3i) \\ = 2 {}^{2} - (3i) {}^{2} \\ = 4 - 3 {}^{2} i {}^{2} \\ = 4 - 9( - 1) \\ = 4 + 9 \\ = 13$

Answer 2

$(2 + 3i)(2 - 3i) = 0\\ 4 - 6i + 6i - {9i}^{2} = 0\\ 4 - {9i}^{2} = 0 \\ {9i}^{2} = 4 \\ {i}^{2} = \frac{4}{9} \\ i = \sqrt{ \frac{4}{9} } \\ i = \frac{2}{3}$

This is your answer mate hope it helps.
