Simplify it first because less work that way.

x%5E2-8x%2B70=0

Can you factor the left member? If not, study, understand, and apply this lesson:

solve 3x^2-24x+210=0 with the quadratic formula?
----
1st:: Simplify to get:
x^2 - 8x + 70 = 0
-----
Then:
x = [8 +- sqrt(64-4*70)]/2
----
x = {8 +- sqrt(-216)]/2
----
x = [8 +- sqrt(-36*6)]/2
-----
x = [8 +- 6sqrt(6)i]/2
---
x = 4 +- 3sqrt(6)i
