Answer:
B. x= 1.82 or x= -0.82
Step-by-step explanation:
Only one approach was necessary to achieve the desired accuracy.
Solutions are x ≈ 1.82 or -0.82.
_____
Ordinarily, I would solve this graphically by rewriting the equation to ...
f(x) = 2x^2 -2x -3
and using the graphing software to find x for f(x) = 0. For even better accuracy than the values shown for the x-intercepts, the vertex coordinates can be used to find the "exact" result. The second attachment shows the solutions to calculator accuracy (0.5±a₁).
