WORKSHEET ON SOLVING QUADRATIC EQUATIONS BY FACTORING

(1) Solve the following quadratic equations by factorization method

(i) 4x² - 7x - 2 = 0         Solution

(ii) 3(p² - 6) = p(p + 5)        Solution

(iii)  √(a(a -7)) = 3 √2        Solution

(iv)  √2x² + 7x + 5√2 = 0      Solution

(v)  2x² - x + (1/5)  =  0    Solution

(2)  The number of volleyball games that must be scheduled in a league with n teams is given by G (n) = (n² - n)/2 where each team plays with every other team exactly once. A league schedules 15 games. How many teams are in the league?         Solution
