hey guys please help me?

Question

Factor x2 + 5x - 24.
A) (x - 4)(x - 6)

B) (x + 3)(x - 8)

C) (x - 3)(x + 8)

D) (x + 4)(x - 6)

Answer 1

find two numbers that add up to give u a +5 and multiply to give you a -24

in this case it will be 8 and -3
so you will have

(x-3)(x+8)

Answer 2

If you don't know how, learn to use FOIL. learn the properties of when you use + and -.
First times first
Outside times outside
Inside times inside
Last times last

so x times x=x^2.
4 and 6, and 3 and 8 are factors of 24. You need the middle to equal +5. 8 and 3 can be added to equal 5 (8 and -3), but 6 and 4 cannot in anyway. So, you have x^2, and the values with positive 8 and negative 3. So, your answer is C.

This is a very necessary skill in all math, so learn it!

Answer 3

x² + 5x - 24

(x + 8)(x - 3)

is C)
.

Answer 4

This question is not that hard. Just ask yourself, "Which of those two integers, if added, will make +5 and, if multiplied, will make -24?"

Just remember, when multiplying the two sets together, the acronym FOIL:

First
Outside
Inside
Last.
