Question

Simplify:
x^2-20x+14
-----------
x+3
what is the integer remainder?

Answer 1

x -23
--------------
x+3 | x^2 -20x +14
-3x
---------
-23x +14
+69
-----
?? <- remainder

Answer 2

for solving this substitue x=-3 in the equation x^2-20+14 and u'll find it...

Answer 3

-3 | 1 -20 14
0 -3 +69
-----------
1 -23 ?? <- remainder :)

Answer 4

the question actually would be , wat is the remainder wen this quadratic equation is divided by x+3, which she wrote like this...

Answer 5

P(x)=x^2-20x+14
P(-3)=9+60+14=83

Answer 6

what uzma said. no reason to divide if you just want the remainder

Answer 7

no reason to divide? lol

Answer 8

woah so whose do i go by?

Answer 9

yea, use remainder theorem

Answer 10

well, only one person actually gave you the answer in the end ....

Answer 11

personally, I was hoping you had enough sense about you to be able to add 14 and 69 ....

Answer 12

yes amistre is right because question said "simplify" a terrible word but i guess in this case it means to actually divide

Answer 13

so if it says "divide" you had best divide!

Answer 14

yeah, I wanted to factor at first lol

Answer 15

because you didn't finish reading the question, just like i didn't read the first part.

Answer 16

so the integer remainder is 83?

Answer 17

yes. amsitre gave you the answer. it is
\[\frac{x^2+20x-14}{x+3}=x-23+\frac{83}{x+3}\]

Answer 18

say it with confidence, it sounds better; the integer remainder is 83! :)

Answer 19

which is another way of saying
\[x^2+20x-14=(x+3)(x-23)+83\]

Answer 20

thanks guys.

Answer 21
