Direction: In the given question, two equations numbered l and II are given. Solve both the equations and mark the appropriate answer.

I. x² – 12x + 32 = 0
II. 2y² – 9y + 10 = 0

The ratio of the side and height of an equilateral triangle is –

P = 12xy – 10y² – 18x²,

Q = 14x² + 12y² + 9xy, and

R = 5y² – x² + xy

then (P + Q) – R =
