The square of x plus 7 times of XY minus 6 times of XY is equal to 0. Find the value of X / y The square of x plus 7 times of XY minus 6 times of x times the square of Y equals 0 to find the value of X / y
The square of x plus seven times XY minus six times the square of XY equals zero
Multiply the two sides by X / Y and#178;, we get: (x / y) ² + 7 (x / y) - 6 = 0, that is
X / y = (- 7 ± root 73) / 2,
