Do you know how to factor \[x^2+11x+28\]

snowflake0531:

Like, not looking at those stuff, an you factor that

Countrygirl123:

no

snowflake0531:

Okay, so, we have x^2 + 11x +28 This means, we have to get 2 factors of 28 that multiply to 28, but also add up to 11 Can you think of them?

Countrygirl123:

4 and 7

snowflake0531:

Yep! So, we have \[x^2 + 11x+28 = (x+7)(x+4)\] so now, can you fill in teh blanks?

Countrygirl123:
