is 2a^2 -5a - 3 = 0
supposed to be the simplified version of
2x^-2 - 5x^-1 - 3 = 0 ??
your first equation would be
2/x^2 - 5/x - 3 = 0
multiply each term by x^2
2 - 5x - 3x^2 = 0
3x^2 + 5x - 2 = 0
(3x-1)(x+2) = 0
x = 1/3 or x = -2
Solve:
2x^-2 - 5x^-1 - 3 = 0
2a^2 -5a - 3 = 0
(2a^2 - ) + ( a - ) = 0
I am stuck here please help.
