Question 639488: Good day
If i have the following matrices :
A=
x^2 +4, log1
a+2 , b
and
B=
4, y
3a-1, -1
To get A=B
the unknowns must assume the following values
A. x = -2 , y = 0 , a = - 3/2 , b = -1
B. x = +2 , y = 0 , a = 3/2 , b = -1
C. x = 0 , y = 0 , a = 3/2 , b = -1
D. x = ±2 , y = 1 , a = -3/2 , b = 1

Thanks
