Question

how do you get the square root of a binomial out of this problem x^2+20x+100

Answer 1

You want to factor each terms using FOIL

Answer 2

our teacher didnt teach us how.

Answer 3

Okay, so first thing; do you know how to factor?

Answer 4

somewhat

Answer 5

Say, if I gave you (a + b)(2 + 2) Could you factor it?

Answer 6

i doubt it i wouldnt now how to factor that. not to good at math.

Answer 7

Fine, you use the foil method. FOIL = First, outer, Inner, Last.

x^2+20x+100
ANS: (x + 10 )(x + 10 )

FOIL

x^2 + 10x+10x + 100
x^2 + 20x + 100, seems to be okay.

Next time I suggest not being so rude when someone is trying to help you.

Answer 8

Oh, pardon me, I misread your comment! You weren't rude. My apologies.

Answer 9

its cool, i still dont understand ill give you an example of a problem in my book so you will know that your doing it right. x^2+10x-3=0 then it shows x^2+10x=3. then x^2+10x+5^2=3+25 then (x+5)=square root of 28 then x=-5 square root of 28 then x=5 plus or minus 2 square root of 7

Answer 10

Okay, and what exactly are you having trouble with?

Answer 11

The equation part? PEMDAS part? Factoring? Expanding?

Answer 12

all of it my teacher, sucks.

Answer 13

i know to write the left side as x^2+bx which is x^2+20x=100

Answer 14

Give me a problem and I'll walk you through.

Answer 15

the first problem i gave u please

Answer 16

I already solved it... You want me to do step by step on how I solved it?

Answer 17

yes please

Answer 18

I found this:

It's very helpful.

Answer 19

thank you

Answer 20

Go down to the quadratic trinomial part

Answer 21

I mean Multiplying Binomials, then read

Answer 22

would the answer be x=10-10 square root of 20?

Answer 23

For: x^2+20x+100?

Answer 24

yes

Answer 25

We pull put them in parenthesis.

( )( ) <---

First we factor x^2, do you know how we can do that?

Answer 26

from the examples in my book none of the answer are in parenthesis thats where you confusing me

Answer 27

Here, read this and then come back to me with questions or concerns:

Answer 28

Not in parenthesis? Give me an example.

Answer 29

its to complicated to type out i really appreciate the effort your giving to try to help me but i cant explain what were doing therefore theres not a whole lot you can do

Answer 30
