x2 − 36y2
Chat with our AI personalities
x2 = 18y2/5 + 10 Or if you want to isolate x: x = ± √(18y2/5 + 10)
y=12
If: 10x2-64 = 36+6x2 Then: 4x2-100 = 0 And: (2x-10)(2x+10) = 0 So: x = 5 or x = -5
If the 64 has a minus sign, then the solution is x = +/-5 Simplifying gives 4x squared = 100 ie x squared = 25...
100-34 equals = 66
