Start with this:
_________
x-2)2x²-3x+8
x goes into 2x² 2x times because ,
so put 2x above the line above -3x
2x
x-2)2x²-3x+8
Multiply 2x by x-2 getting 2x²-4x and put it underneath
2x²-3x and draw a line underneath it:
2x
x-2)2x²-3x+8
2x²-4x
Now subtract (2x²-3x)-(2x²-4x) = 2x²-3x-2x²+4x = -3x+4x = x and
write that under the line:
2x
x-2)2x²-3x+8
2x²-4x
x
Now bring down the next term +8
2x
x-2)2x²-3x+8
2x²-4x
x+8
x goes into x 1 time because ,
so put +1 above the line above +8. [There MUST
ALWAYS BE a sign placed between every two terms.]
2x+1
x-2)2x²-3x+8
2x²-4x
x+8
Multiply +1 by x-2 getting x-2, and write it underneath
x+8 and draw a line underneath it:
2x+1
x-2)2x²-3x+8
2x²-4x
x+8
x-2
Finally subtract (x+8)-(x-2) = x+8-x+2 = 10, so write 10
below the bottom line:
2x+1
x-2)2x²-3x+8
2x²-4x
x+8
x-2
10
We place the remainder 10 over the divisor x-2 and add that fraction
to the quotient.
The answer is
