Answer:
a) subtracting '8' on both sides, we get
- 5 x² + 8-8 = 133-8
- 5 x² = 125
b) The solution is x = 5 i
Step-by-step explanation:
<em>Explanation</em>:-
<u><em>Step (i):</em></u>-
Given quadratic equation - 5 x² + 8 = 133
subtracting '8' on both sides, we get
- 5 x² + 8-8 = 133-8
- 5 x² = 125
<u><em>Step(ii)</em></u>:-
dividing '-5' on both sides, we get

x² = -25

x = 5 i
