Answer:
x = 1 − √63i / 4 , x = 1 + √63i / 4
Step-by-step explanation:
Let's use the formula −b±√b2−(4ac) / 2⋅a
= ax^2+bx+c=0
= 2x^2-x+8=0
Let's substitute 2 for a, −1 for b, and 8 for c in the formula of quadratic equation.
x = −1±√−12−(4⋅2⋅8) / 2⋅2
x = 1±√1−64 / 4
x = 1±√−63 / 4
x = 1±√63⋅−1 / 4
x = 1±√63√−1 / 4
x = {1−√63i / 4 , 1±√63i / 4}
