a
Quadratic formula, completing the square or graphing; the coefficient of x2-term is 1, but the equation cannot be factored.
b
Quadratic formula, graphing; the equation cannot be factored easily since the numbers are large.
c
Square roots; there is no x-term.
d
Factoring; the equation is easily factored.
The answer would be a. Quadratic formula, completing the square or graphing; the coefficient of x^2-term is 1, but the equation cannot be factored.
Since the equation cannot be factored easily, we can consider other methods to solve it. The quadratic formula is a reliable method to solve quadratic equations and can be used in this case. Alternatively, completing the square or graphing can also be used to find the solution.
