Question

What does it mean to write the expression x^2 + 2x - 24 as a product of two linear expressions?

Answer 1

factor

Answer 2

So just factor it? That is it?

Answer 3

yep

Answer 4

I thought all that fancy text was supposed to mean something? All well, that is pretty easy!!!

Answer 5

Thanks for the help!!!

Answer 6

factor of that equation would be like (x-b)(x+b)
which is same as linear equation y=mx+b

Answer 7

np o^_^o

Answer 8

Does all this fancy text also just mean to factor?

Rewrite x^2 - 8x + 16 as a square of a linear expression.

Answer 9

lol i feeeel ya ;-^

Answer 10

yes right
there is a word `square` that means u answer would be (x-h)^2
you will get same parentheses
here is an example
x^2+4x+4

we need two number when we multiply them we should get product of AC =4 times 1 =4
and when we add/subtract them we should get middle which is also 4 in this question
so 2 times 2 =4
2+2=4
factors are (x+2)(x+2) which can be written as (x+2)^2

Answer 11

So would x^2 + 2x - 24 be (x-4)(x+6)?

Answer 12

6 times -4 = -24 yes
6-4 =2 so yes

Answer 13

And so x^2 - 8x + 16 should be (x-4)^2, correct?

Answer 14

how ? explain plz :=)
