a)5x2 + 8x + 7 = 0
b)(7)1/2y2 – 6y – 13(7)1/2 = 0
c)2x2 + x – 1 = 0
d)4/3x2 – 2x + 3/4 = 0
e)2x2 + 5x + 5 = 0
f)p2 – 4p + 4 = 0
g)m2 + m + 1 = 0
h)3z2 + z – 1 = 0




I could not make some of the numbers small like they are to be. In each equation at the begining the 2,s are to be small and above the letter. and the two1/2's above both (7) is also to be small above the (7).

Two theoreticaly IDENTICAL pumps set at the same pressure, pumping the exact same fluid, but the temperature of the fluid is the only difference. Why will the pump "pushing" the cold fluid pass more volume?

How do you rewrite this quadratic equation to equal 0

x^2 = 3x +12

After that how do you set it up in the quadratic formula


For this equation ........ x^2 +16x +60

I have figured out that that answer is (x,10) and (x,6) however I am confused now how to set this up in the quadratic formula.

Completely hypothetical question. Let's all ignore the fact that tachyons are only theoretical. Furthermore, let's assume the following (believed) parameters:
1) Tachyons have an imaginary number mass.
2) Because of #1, tachyons travel faster than light.
3) Because of #2, they travel backwards through time.

If a photon and a tachyon were emitted simultaneousely towards a target, which one would get there first? Sure, the tachyon travels faster than a photon, but it also travels backwards through time. Would this time dilation affect the outcome of the race (i.e. would it cause the tachyon to reach the target before being emitted)? Furthermore, what is this answer relative to? Is the answer from the tachyon's local spacetime or the photon's.
