Question:
Linear Algebra: Quadratic Polynomials and Complex Coefficients
Question Details:
a) Write the expression in the form a+bi for a,b,in R. α=5
b) Solve quadratic equation 2x2 + ( 2+10i ) x + (-4 + 5i ) = 0
Simplify as much as possible.
Hint: The formula for the roots of a quadratic polynomial also holds for quadratic polynomials with complex coefficients.
