Question

Part B In part A you simplified the expression 4+ 16 - (4)5) What other type of expression does this expression remind you 2 of? What concepts have you learned about in the past that complex numbers can help with?​

Answer 1

The expression in part A is similar to the quadratic formula. So, it’s likely that complex numbers can help us solve quadratic equations that have imaginary solutions and that we would have labeled as having no solution if using only real numbers.
