In CPU design, what does the Control Unit (CU) primarily

I. 6x² + 19x + 10 = 0

II. y² + 10y + 25 = 0

I. 2x²– 25x + 33 = 0

II. 3y²+ 40y + 48 = 0

Solve the quadratic equations and determine the relation between x and y:

Equation 1: x² - 54x + 704 = 0

Equation 2: y² - 44y + 448 = 0

I. 8x² + 2x – 3 = 0

II. 6y² + 11y + 4 = 0

I. 84x² - 167x - 55 = 0

II. 247y² + 210y + 27 = 0

I. 3q² -29q +18 = 0

II. 9p² - 4 = 0

I. 8x – 3y = 85

II. 4x – 5y = 67

I.8^(x+3)+ 8^(-x)=72 

II. 5^(y+5)+ 5^(-x)=150 

I. 63x² + 146x + 80 = 0

II. 42y² + 109y + 70 = 0

I. 15y²+ 26y + 8 = 0

II. 20x²+ 7x – 6 = 0
