get A and B which make ( AX + BY ) ² = X (4 Y - 3 X ) + 1 an equation for a circle and then get the centre and the radius .help please
A²X²+2ABXY+B²Y²=4XY-3X²+1(A²+3)X²+(2AB-4)XY+B²Y²=1∴2AB-4=0 AND A²+3=B² AND CENTER IS (0,0)X²/P²+Y²/P²=1 WHERE 1/P²=A²+3=B² X²+Y²=P² SO THE RADIUS IS PA=2/B, 4/B²+3=B²=DEF=X 4/X+3=Xyou can go on from here
excuse me can you finish it please ?it sometimes seems difficult for me to translate that to arabic u know ... sorry everybody for botering
4/X+3=X4+3X=X² (X-4)(X+1)=0X=4 and radius r=√x=2center is O, (0,0)
