-112 - 56 : x^2 = -126
56 : x^2 = -112 - (-126)
56 : x^2 = 14
x^2 = 56 : 14
x^2 = 4
x = 2
-112 - 56 : x2 = -126
-56 : x2 =-112 -126
- 56 : x2 = - 228
x2 = -228 * -56
x2 = 12768
=> x = \(\sqrt{12768}\)= \(4\sqrt{798}\)
-112-56:x^2= -126
\(\Rightarrow\)-56:x^2= -126+112
\(\Rightarrow\)-56:x^2= -14
\(\Rightarrow\)x^2 = -56:(-14)
\(\Rightarrow\)x^2 = 4
\(\Rightarrow\)
-112 - 56 : x2 = -126
56 : x2 = -112 + 126
56 : x2 = 14
x2 = 56 : 14
x2 = 4
x = 2
