To solve for x in the equation x²-6x-16=0, factor the equation, and solve for x.
x²-6x-16=0
Find 2 numbers that when added to each other equal -16 and add up to -6
-8 and 2 (these will be the factors of the equation)
Rewrite the equation
(x-8)(x+2)=0
Solve for x by setting each apart and getting x "by itself"
(x-8)=0
Add 8 on both sides
x= 8
(x+2)=0
Subtract 2 on both sides
x=-2
x= 8, -2

Answer:
the movement of water from low concentration area to high concentration area is known as Diffusion.
And if the movement is from the area of high concentration to low concentration when a membrane is present in between them then it is called osmosis
The movement of water from low concentration of area to high concentration area energy is known as Active movement.
Active movement energy is needed for the movement of the water.
At a fundamental level, water provides electrons to replace those removed from chlorophyll in photosystem II. Also, water produces oxygen as well as reduces NADP to NADPH (required in the Calvin cycle) by liberating H+ ions
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
Water also has another important role of being an electron feeder. In the process of photosynthesis, water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon (of carbon dioxide) to give sugar (glucose).
Water acts as a reducing agent by providing H+ ions that convert NADP to NADPH. Since NADPH is an important reducing agent present in chloroplasts, its production results in a deficit of electrons, resulting from oxidation of chlorophyll. This loss of electron must be fulfilled by electrons from some other reducing agent. Photosystem II involves the first few steps of the Z-scheme (the diagram of the electron transport chain in photosynthesis) and therefore a reducing agent that can donate electrons is required to oxidize chlorophyll, which is provided by water (acting as a source of electrons in green plants and cynobacteria). Hydrogen ions thus released create a chemical potential (chemiosmotic) across the membrane that finally results in synthesis of ATP. Photosystem II is the primary known enzyme that acts as catalyst in this oxidation of water.
