2px² + 2qxy + 3ypx + 3qy² = rx² + 23xy + 12y²
Dari persamaan 3qy² = 12y² didapat :
3q = 12
q = 4
Masukan ke 8xy + 3ypx = 23xy
( 8 + 3p )xy = 23xy
8 + 3p = 23
3p = 15
p = 5
Masukan lagi :
2px² = rx²
10x² = rx²
r = 10
2px² +2qxy +3pxy +3qy² = rx² +23xy +12y²
r = 2p
2q +3p = 23
3q = 12
> 3q = 12
q = 4
> 2q +3p = 23
2 (4) +3p = 23
8 +3p = 23
3p = 15
p = 5
> r = 2p
r = 2 (5)
r = 10
Jadi, nilai r pada persamaan bentuk Aljabar tersebut adalah 10.
