X^2 - 2x - 8 = 0
(x - 4)(x + 2) = 0
x = 4 or x = -2
The positive root is x = 4

<h3>What is Photosynthesis?</h3>
Plants and other living things transform light energy into chemical energy through a process called photosynthesis, which can then be produced through cellular respiration to energize the organism's activities. The majority of species are photoautotrophs, as are all plants, algae, and cyanobacteria. The production and maintenance of the energy required for life on Earth, as well as the production and maintenance of the oxygen content of the atmosphere, are primarily accomplished via photosynthesis.
