Question
If X=2 is a root of 2X^3+5X^2-23X+10=0, find the remaining roots. How to I do this
(x - 2)(x + 5)(2x - 1)
Using synthetic division
2'|'2'5'-23'|''10
''|'''4''18'|'-10
-------------------
''''2'9''-5'|'''0
Written out, you get
2x^2 + 9x - 5
this factors to (x + 5)(2x - 1)
The easiest way to find out if what you did is correct rather it is in the book or not
