Question

What are the factors of x^2 + 10x + 24?

(x − 12)(x − 2)

(x + 12)(x + 2)

(x + 4)(x + 6)

(x − 4)(x − 6)

Definitely not the first one, right @hartnn

Answer 1

yeah, not the first...
can you tell me 2 numbers whose sum is 10 and product is 24 ?

Answer 2

6 and 4

Answer 3

correct!
so, split 10x as 6x+4x
x^2+6x+4x+24
can you factor this ?
factor out x from first 2 terms and 4 from last 2...

Answer 4

x^2+6x+4x+24
x(x+6)+4(x+6)
(x+4)(x+6)
x=-4,-6

Answer 5

so 3rd is correct

Answer 6

Oh.. Okay, thanks. @hartnn and @nirmalnema ! :D
