(6y - 11)(6y + 11) = ay
² - b    |use (a - b)(a + b) = a² - b²
(6y)² - 11² =ay² - b
36y² - 121 = ay² - b    |add b to both sides
ay² = 36y² - 121 + b        |divide both sides by y² ≠ 0
a = (36y² - 121 + b)/y²
 
 
        
        
        
The Last on = 45x^2 - 2x - 8
Reason being is because you would group and multiple:
(9x - 4) • (5x +2)
