Solve for x:69/4 - 9 x + X^2 = 0
Bring 69/4 - 9 x + X^2 together using the common denominator 4:1/4 (69 - 36 x + 4 X^2) = 0
Multiply both sides by 4:69 - 36 x + 4 X^2 = 0
Multiply both sides by -1:-69 + 36 x - 4 X^2 = 0
Add 4 X^2 + 69 to both sides:36 x = 4 X^2 + 69
Divide both sides by 36:Answer:  x = X^2/9 + 23/12
