I do not understand how they got the answer to a problem. Could you please explain how the answer was attained:
Perform each division:
:
(2x^3 - 10x^2 + 3) / (x^2-1)
:
you have to have each degree of the equation represented,
add O coefficients, if necessary
:
In your equation:
(2x^3 - 10x^2 + 0x + 3) / (x^2 + 0x - 1)
:
Using long division (used.... to keep thing lined up here)
:
......................................................2x - 10
.........................----------------------------
(x^2 + 0x -1) |2x^3 - 10x^2 + 0x + 3
...........................2x^3 + 0x^2 - 2x
..............................----------------------
.....................................-10x^2 + 2x + 3
.....................................-10x^2 + 0x + 10
.....................................-----------------
...................................................2x - 7
