Answer:
The solutions x=4±85√2 must be left in exact form.
Step-by-step explanation:
The quadratic formula -b ±√b^2- 4ac/2a will always give us solutions in the form; m±n√q, where m,n and q are integers.
These solutions must always be presented in its exact form, that is, with the square roots in it. Hence the solutions x=4±85√2 are in its exact form.
