What method(s) would you choose to solve the equation: x^2 + 2x - 6 = 0 a )quadratic formula, graphing; the equation cannot be factored easily since the numbers are large. b) quadratic formula, completing the square or graphing; the coefficient of x2 term is 1, but the equation cannot be factored. c) square roots; there is no x-term. d) factoring; the equation is easily factored.

It would be B.  "Regular" factoring without the quadratic formula can't be done.  Completing the square will work easily since the coefficient on the squared term is a 1.  I personally wouldn't graph this to find the solutions, although you could with and x/y chart to give you enough coordinates to plot the graph correctly.

a = -3/4

Step-by-step explanation:

1/64 = 16 ^(2a)

4^ -3 = 2^4 ^(2a)

4^-3  =2^(8a)

The bases are not the same so the exponents cannot be equated yet

2^2^-3 = 2 ^(8a)

2 ^ (-6) = 2 ^(8a)

Now the bases are the same so we can equate the exponents

-6 = 8a

Divide each side by 8

-6/8 =a

-3/4 =a
