Assignment:
Show your work step by step. Determine the constant that should be added to the binomial so that it becomes a perfect square trinomial. Write and factor the trinomial.  
Q1.   x^2 + 16x
Q2.   x^2 + 5x
Q3.   x^2 + 4/5 x
                
Show your work step by step.  Solve each equation by completing the square.
Q1.   x^2 + 6x = -8
Q2.   x^2 – 2x – 5 = 0
Q3.   x^2 + 7x – 8 = 0
Q4.   2x^2 + 5x – 3 = 0
Q5.   3x^2 – 5x – 10 = 0
Provide complete and step by step solution for the question and show calculations and use formulas.
