Question
Noah and Lin are each trying to solve the equation a-6r +10 = 0. They know that the solutions to a =-1 arei
and -i, but they are not sure how to use this information to solve for in their
equation.
Lin decides to solve the equation using the quadratic formula. Here is her work:
-btVb2-4ac
2a
-(-6)tV(-6)-4(1)(10)

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.
