Question

Which model represents the factors of x2 + 9x + 8?

Answer 1

we can write the above equation as
x^2 + 8x+x + 8
=x(x+8) + 1(x+8)
=(x+1)(x+8)
this is the factor of it

Answer 2

Thank you for asking this question:

⇒  ( x + 1 )  ( x + 8 )

⇒  x ²+ 9 x + 8

Here we are supposed to find the two factors of 8 and the sum of factors is 9.

And the factors of 8 are:

= 1,8 ⇒  1 + 8 = 9

= 2,4 ⇒ 2 + 4 = 6

The factors of 1 and 8 give us a sum of 9

So,

x² + 9x + 8 = (x+1)(x+8)
