Math Problem Statement

Find the value of x and the value of y in the following equation, give that

π‘₯(1 + 𝑖)

2 + 𝑦(2 βˆ’ 𝑖)

2 = 3 + 10𝑖 where π‘₯ ∈ 𝑅 π‘Žπ‘›π‘‘ 𝑦 ∈ 𝑅

B) Given that 𝑧 = βˆ’3 + 4𝑖 π‘Žπ‘›π‘‘ 𝑧𝑀 = βˆ’14 + 2𝑖, find

𝑖) 𝑀 in the form π‘Ž + 𝑖𝑏, where π‘Ž π‘Žπ‘›π‘‘ 𝑏 are real numbers.

𝑖𝑖) the modulus and the argument of 𝑀.
