Question

9x^2-25

Answer 1

(3x - 5)(3x + 5)

Answer 2

9x^2, 3 x 3 = 9
x * x = x^2

Answer 3

5 x 5 = 25
-5 x 5 = -25

Answer 4

That's what makes these so easy. Lol.

Answer 5

\(\bf 9 = 3^2 \qquad \qquad 25 = 5^2 \qquad \qquad (a-b)(a+b) = (a^2-b^2)\)

Answer 6

I put a lot of work into this question, mind giving me a medal?

Answer 7

Wolf, I wanted to see what you were going to say. Say it already.

Answer 8

Thanks you

Answer 9

x=+-sqroot(4*9 *-25) / 18
x = +-sqroot(900) / 18
x = 5 / 3
x = -(5/3)
That's the answer I get.

Answer 10

Lol.

Answer 11

This type of question is asking for factoring. Wolf, you can't get any answer like that without a variable/number that is equal to the equation.

Answer 12

All I saw was a quadratic equation and proceeded to solve it.

Answer 13

Lol. Wolf.

Answer 14

Well I didn't specifically see a "Factoring Only" sign attached to the equation. LOL

Answer 15

Besides, you've got a 61 rating, I only have a 60.

Answer 16

Lol, rating has no meaning to me.

Answer 17

So with the directions involving factoring the answer would be (3x-5) (3x+5)?

Answer 18

Lol yes. His answer was dumb, he doesn't understand the question.

Answer 19

Well. Thank you.

Answer 20

Um.

Answer 21

What lol

Answer 22

I was wondering if you could help me with x^3+27

Answer 23

(x + 3)(x^2 - 3x + 9)

Answer 24

How do you get that though?

Answer 25

Why wouldn't it be (x+3)(x^2+9)?

Answer 26

That doesn't equal x^3 + 27. Lol.

Answer 27

I have see hundreds of equations and factors which I already know In my head. It's like pi. I memorize certain numbers times pi equals this output.

Answer 28

How do you get the -3x part?

Answer 29

It's how you get the 3 x's to multiply.

Answer 30

to have x^3

Answer 31

Mickey1992 - gee you make a reference to "his answer was dumb" anyone in particular you had in mind when you said that?

Answer 32

You're answer was pathetic, your knowledge on this subject is sad. I'm trying to help this person, but you inform him/her wrong information and confuse him/her.
