MATH QUESTION!!! ?

Question

2x + x{squared} = 24

Answer 1

x^2 + 2x - 24 = 0

(x+6)(x-4) = 0

x = -6 or x = 4

Answer 2

x^2 + 2x - 24 = 0

(x + 6)(x - 4) = 0

x= -6, 4

Answer 3

First of all this is an equation at the second degree as you subtract 24 from the right side you will have :

2x + x^2 - 24 = 0

to have a better view, arrange the x^2 (x{squared}) at the first place then the 2x that will make :

x^2 + 2x - 24 = 0

Call a=the number of times * x^2

      b = the number of times * x

     c= -24

you will have o(delta) = b^2 - 4ac = 2^2 - 4*(-24)*1 = 100 <=> makes 10

Next using delta you will have 2 solutions for x : let's call them X (it's easier)

X1 = ( -b+delta)/2a

X2 = (-b - delta)/2a

Replace them and you'll have

X1 = 4

X2 = -6

Well that's the solution, hope it helps ;))!!!
