Answer 1

Please explain

Answer 2

You missed an x.

Answer 3

x2 + 3x = 124?

Answer 4

No i didn't thats what the equation says

Answer 5

x2 + 3 = 124
x^2 +3 - 124 = 0

x^2 - 121 = 0
NOT it's differences of squares.
use the formula,
(a^2 - b^2 ) = (a+b)(a-b)

x^2 - 121 =0
(x-11)(x+11) = 0

Answer 6

so it doesnt have an answer??

Answer 7

x2 + 3 = 124
Then x*2 = 121 and x= 60,5
Or did you mean x^2?
Then it's x^2-121= 0 = (x-11) (x+11) = 0
X=-11 and +11
