Question

turn x^2-12x+36 into this format
(x +- x) (x +- x)

Answer 1

pls help

Answer 2

First, that is horrible notation. The symbol 'x' is used in at least two different ways. Very confusing.

This might be better:

(x +/- a)(x +/- b) where a*b = 36

Answer 3

Also, a + b = -12

This gives us a clue. We can no refine the form:

(x - a)(x - b) where a*b = 36 and a + b = -12

You must see why this is so before proceeding.

Answer 4

ok i see

Answer 5

i see where did you go

Answer 6

explain better if you understand.

Answer 7

it would be (x +- (a)
multiple of 36) (x +- (b)multiple of 36)

Answer 8

It's fine the way it was.

(x - a)(x - b) where a*b = 36 and a + b = -12

For a*b = 36, we have these possiblities:

-36 * -1
-18 * -2
-12 * -3
-9 * -4
-6 * -6
36 * 1
18 * 2
12 * 3
9 * 4
6 * 6

For a + b = -12?? Can we find a pair that does that?
