Q. The no. of distinct pairs of (a, b) real numbers that would satisfy and .
A-5
B-12
C-3
D-7
dont laugh anyone on such elementary question....help!!
I've found 5 pairs of real numbers (and 2 pairs of complex numbers).
All results containing y = 0 satisfy the second equation. From the first equation you'll get 3 different values of x if y = 0.
From the second equation you find out that must be a possible x-value. Plug in this value into the first equation and calculate the corresponding y-values.
