If the answer is irrational, please give the answer as a simplified radical, not as a rounded decimal.

x^2 + 3x = 12




The following equation is in Standard form.

Put the equation in General form by completing the square.

Tell the vertex of the parabola.

Please use ^ for exponents.

f(x)= x^2 - 4x + 7

1. i^5

2. sqrt - 32 (remember to deal with the negative under the radical first)

3. sqrt - 25 - sqrt - 49

4. (-3i)(2i)

5. (7 sqrt -3)(2 sqrt -27)

6. sqrt -24 / sqrt - 2

thank you all so much. if anyone solves all of them i will most definetly award a best answer.

Suppose that we have a regular polygon with 'n' sides. 'M' is an arbitrary point in this polygon whose distance from the sides of the polygon are 'x_1', 'x_2', ..., 'x_n'.

Show that this equation holds:

When 2x^(2a) + 11(x^a)(y^b) - 6y^(2b) is factored, one factor is:

2x^(2a) - 3y^b

x^(2a) + 2y^b

2x^a + y^b

x^a + 6y^b

none of these

For example in parametrics...where you dont necessarily have strict functions. How do you find that vertical tangent out manually (instead of just looking at the graph on a calculator)?
