Because the coefficient of x^2 is -1, we know that a will be -1.  Knowing that the coefficient of x is -4, we can calculate that p=2.  Thus, we have -1(x+2)^2+q is our equation.  This is equal to -x^2-4x-4+q.  As the constant term must be 2, we can then see that q is 6.

As such, we have -1(x+2)^2+6=0 as our factorization.

To solve this equation, we can use the quadratic formula.  Plugging in values, we have:

\frac{4+-2 \sqrt{6} }{-2}
which is equal to: (when the fraction is simplified)
-2+- \sqrt{6}

When an exponent is raised to another exponent, you can multiply the powers to simplify them.

3/8*3/4

<em>*Multiply numerators*</em>

3*3=9

<em>*Multiply denominators*</em>

8*4=32

x^9/32

Hope this helps!!
