Simplify the difference a^2-2a-3/a^2-9a+18 - a^2-5a-6/a^2+9a+8.

the answer is:

in a biology class, the teacher started explaining a new lesson about the dna structure. personally, i found this lecture hard to understand. so i decided to use my critical thinking skills to be able to understand it. i analysed the different ideas, and broke them down into smaller parts to assimilate each. then i started evaluation and tried to link what i am learning with real life experiences so that i can make sure that i know how everything i am learning relates. finally, i started questioning by researching more what i learned and asking more questions that can me through my learning process. reflecting on the information meant that i should review it. all this me greatly understand what i previously found hard to understand.

hope it !

ok

explanation:

eggs are a high protein food! dan is most likely to include them in his diet. according to my sources, "whole eggs are among the healthiest and most nutritious foods on the planet. they are loaded with vitamins, minerals, healthy fats, eye-protecting antioxidants and brain nutrients that most people don't get enough of. whole eggs are high in protein, but egg whites are almost pure protein."
