Question

Someone please help me!!

[9.02] What are the solutions of x^2+5x−24=0? Show all work for full credit.

Answer 1

i dont understand how to do it

Answer 2

What two numbers can multiply together to give you -24 ?
Then see if you can add or subtract these two numbers to give you +5

Answer 3

-6x4

Answer 4

Or you could use the quadratic formula to solve this quadratic equation

Answer 5

solutions are: (x-3)(x+8)

Answer 6

ok. So can you add or subtract -6 and 4 to give you 5?
If we try -6 + 4= -2
and if we try -6 - 4 = -10
So these two numbers don't work.

Answer 7

radelp is right

Answer 8

Let's try -3 and 8.
-3 x 8 = -24 so that works :)
Now we try to add or subtract -3 and 8.
So -3 + 8 = 5
So that means those are your answers and you would write it as
(x-3) (x+8) = 0
Then solve for x

Answer 9

So now we want (x+3) = 0
This means x = -3
Because -3 + 3 =0
and then we do the same thing for (x+8) =0
So x=-8

Answer 10

im still confused on how you got that...

Answer 11

have you heard of the FOIL method?

Answer 12

no..

Answer 13

First outter inner last
