Answer:
1.
2. Quadratic formula is the most efficient way to solve this equation.
Step-by-step explanation:
We have been given an equation . We are asked to solve our given equation using quadratic formula.
, where,
b = Coefficient of x term,
c = Constant,
a = Coefficient of term.
Upon substituting our given values, we will get:
Therefore, the solutions for our given equation are .
2. We cannot factor our given equation by splitting the middle term because there are no such numbers which add up-to 6 and whose product is 6.
Therefore, the quadratic formula is the most efficient way to solve this equation.
