Answer:
x²+6x+5=0
On comparing with the equation
ax² + bx + c = 0
a=1, b = 6 and c = 5
Now
b²– 4ac = 6² – 4 x 1 x 5 = 36 - 20 = 16
All of the above.
The properties of water are:
1) polar molecules
2) regulates temperature
3) universal solvent
4) high surface tension
5) can exist in all three stages of matter
Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in.
Polonium<span>The half-life for these elements is measured in mere minutes! Contrast this with the half-life of polonium, which is 138.39 days. According to the Periodic Table of Radioactivity, at this time the most radioactive element known to man is element number 118, which has the placeholder name Ununoctium.</span>
