Question 1108540: can some one explain to me in the simplest form what it means to simplify and how to simplify with an add of the following question. l am seriously looking for a tutor for l dont want given answers but a teacher/ tutor to guide me.
question 1
Simplify the following expression as far as possible:
2y
2
(x − 1) − 8x
y
2 + 1
You can put this solution on YOUR website! 2y is already in simplest form
2 is already in simplest form
(x-1)-8x can be simplified by combining the "x" with the "-8x" to get -7x. The result is -7x-1. This is called "combining like-terms."
y is already in simplest form
2+1 can be simplified to 3 by adding the two numbers
—————————————————————————————
Simplification just means manipulating the expression to get it to its simplest form.
Do note that any higher-power terms in x , , etc. are simplified separately from the and constant terms.
For example simplifies (step by step) as follows:
= <<< changed sign of 2nd paren's contents (multiplied the contents of the 2nd paren's by -1 and removed the parens. )
= <<< just to show you how the coefficients add together. Normally you will do this math in your head, usually starting with the highest power of x and working your way down.
= <<< notice there is no because we ended up with 0*x
