4x²-4a²x+(a4-b4)=0 |
|
Answer» 4x²-4a²x+(a⁴-b⁴)=0or, 4x²-2{(a²+b²)+(a²-b²)}x+(a²+b²)(a²-b²)=0or, 4x²-2(a²+b²)x-2(a²-b²)x+(a²+b²)(a²-b²)=0or, 2x{2x-(a²+b²)}-(a²-b²){2x-(a²+b²)}=0or, {2x-(a²+b²)}{2x-(a²-b²)}=0Either, 2x-(a²+b²)=0or, 2x=a²+b²or, x=(a²+b²)/2Or, 2x-(a²-b²)=0or, 2x=a²-b²or, x=(a²-b²)/2∴, x=(a²+b²)/2, (a²-b²)/2 Ans |
