Let's do synthetic division, and if we're dividing by x plus 2, we put negative 2 in the box, and then the coefficients from the polynomial we're dividing in two go in a row.
00:12
So we have 3x to the 4th, 5x cubed, negative 1x squared, 1x, and negative 2.
00:18
And the procedure is you bring down the first number, so bring down the 3, multiply it by the number in the box, we get negative 6, write it in the next spot, and add the column.
00:28
We have negative 1.
00:29
Multiply that by the number in the box, we get 2, write it in the next spot, and add the column.
00:34
We have 1.
00:35
Multiply that by the number in the box, we get negative 2.
00:37
Write in the next spot, add the column, we have negative 1...
