Hey there!
[tex]\bold{x^2+2x-24=0}[/tex]
- Firstly, you have to work out (factor out) the left side of your equation
- [tex]\bold{Like:(x-4)(x+6)=0}[/tex]
- Since, we are working factoring, let's set your numbers to [tex]\bold{0}[/tex]
- [tex]\bold{Like:x-4=0}[/tex] [tex]\bold{or}[/tex] [tex]\bold{x+6=0}[/tex]
- [tex]\uparrow[/tex]After solving the equation we just created, we should have the value(s) of the [tex]\bold{x-values}[/tex] [tex]\downarrow[/tex]

Answer:
x = 4 x=-6
Step-by-step explanation:
x^{2} + 2x - 24 = 0
Move the constant to the right
x^2 +2x -24+24 = 24
x^2 +2x = 24
b =2
We take b/2 and then square it
2/2 =1 1^1 =1
Add 1 to both sides
x^2 +2x+1 = 24+1
The left side is (x+b/2)^2
(x+1)^2 = 25
Take the square root of each side
sqrt((x+1)^2 ) = ±sqrt(25)
x+1 = ±5
Subtract 1 from each side
x+1-1 = -1±5
x = -1±5
x = -1+5 and x= -1-5
x = 4 x=-6
