Noah and Lin are each trying to solve the equation 2² - 6x + 10 = 0. They know that the solutions to z? = -1 are i and –i, but they are not sure how to use this information to solve for z in their equation.
Lin decides to solve the equation using the quadratic formula. Here is her work:
X
-btvb2-4ac
2a
-(-6)/(-6)2-4(1)(10)
X
2(1)
61V36-40
Lin knows 36 – 40 is a negative number and isn't sure what to do next. Show how Lin can write her solution
using i.
