Noah and Lin are each trying to solve the equation x2 - 6x + 10 = 0. They know that the solutions to 3? = -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:
2
-DIVb2-4ac
20
-(-6)/(-6)2-4(1)(10)
2(1)
6+436-40
x
2
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
