The equation 9x ²  + 4y ²  = 36  represents an

I. p² +7p + 10 = 0 II. q² - q – 6 = 0

Equation 1: x² - 45x + 500 = 0

Equation 2: y² - 60y + 600 = 0

I. 5x + 2y = 31

II. 3x + 7y = 36

I. x² – 10x + 21 = 0

II. y² + 11y + 28 = 0

I. 6 y² + 11 y – 7= 0

II. 21 x² + 5 x – 6 = 0

1.3wx = 40 – wy

2. b² = 2b + p

3. d² + d = q

Now, observe the given conditions:

Equation 1: 2x² - 21x + 54 = 0

Equation 2: 4y² - 23y + 15 = 0

I. 22x² - 97x + 105 = 0

II. 35y² - 61y + 24 = 0

I. p² - 10p +21 = 0

II. q² + q -12 = 0

I. x² + 11x + 24 = 0

II. y² + 17y + 72 = 0
