What is the clock signal's role in sequential

I. 3x² = 2x² + 9x – 20

II. 3y² = 75

I. p²+ 2p – 8 = 0 II. q² – 5q + 6 = 0

I. 8x² - 74x + 165 = 0

II. 15y² - 38y + 24 = 0

I. 2x² + 11 x + 15 = 0    

II. 2y² - 19 y  + 44 = 0    

I. x² – 18x + 81 = 0

II. y² – 3y - 28 = 0

I. 96x² + 52x - 63 = 0

II. 77y² + 155y + 72 = 0

l). p² - 29p + 204 = 0

ll). q² + 4q - 221 = 0

A and B are the roots of equation x² - 13x + k = 0. If A - B = 5, what is the value of k?

(i) 2x² – 9x + 10 = 0

(ii) 4y² – 12y + 9 = 0

I. 35x² - 46x – 16 = 0

II. 35y² - 116y + 96 = 0
