The answer is 10x2= 20
x2 − 36y2
17
The discriminant is 609.
-20 = -4x - 6x-20 = -10x20 = 10x2 = x
10x2 - 29x = 21 10x2 - 29x - 21 = 0 so x = -0.6 or x = 3.5
The answer is 10x2= 20
10x2 - 56 = 88 - 6x2 : 10x2 + 6x2 = 88 + 56 : 16x2 = 144 : x2 = 9 : x = ± 3
x2 − 36y2
17
The discriminant is 609.
10x2 - 64 = 36 + 6x2; whence, 4x2 - 100 = 0, x2 = 25, and x = ±5.
$10x2/3
It's obvious. Just add 10+10. And that equals 20. It is the same as 10x2=20.
-20 = -4x - 6x-20 = -10x20 = 10x2 = x
10x2 +4x + 21 = 0=> 4*x +10*x^2 +21 = 0Complex roots:Root 1: -0.2-1.435 * iRoot 2: -0.2+1.435 * i
If: 10x2-64 = 36+6x2 Then: 4x2-100 = 0 And: (2x-10)(2x+10) = 0 So: x = 5 or x = -5
