X = √63
a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
If I have this correct you are asking x^2 + 10^2 = 12^2 Then x=6.633249507108
12 squared plus 18 squared is equal to 468.
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
X=-3
It also equals 13 12.
It is a quadratic equation in X, with two real roots.
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
133
X = √63
4 squared minus 2 squared equals 12
a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
