Answer with explanation?

Noah and Lin are each trying to solve the
equation - 6z + 10 = 0. They know that the
solutions to 7
=-1 are and -, 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:
-b土Vb-4ac
2a
(6)±/(6)*-4(1)(10)
2(1)
6土V36-40
Lin knows 36 - 40 is a negative number and
isn't sure what to do next. Show how Lin
can write her solution using ..
