Solve x/ x-2 + x+2/ x >2

Answers

Answer 1

Answer: $(x)/(x - 2) + (x + 2)/(x) \ \textgreater \ 2$
$(x(x))/(x(x - 2)) + ((x - 2)(x + 2))/(x(x - 2)) \ \textgreater \ 2$
$(x^(2))/(x(x - 2)) + (x^(2) - 4)/(x(x - 2)) \ \textgreater \ 2$
$(x^(2) + x^(2) - 4)/(x(x - 2)) \ \textgreater \ 2$
$(2x^(2) - 4)/(x(x - 2)) \ \textgreater \ 2$
$2x(x - 2) \ \textgreater \ 2x^(2) - 4$
$2x^(2) - 4x \ \textgreater \ 2x^(2) - 4$
$-4x \ \textgreater \ 4$
$x \ \textgreater \ -1$

Answers

Answer:

Everything will be split in threes. You can do this by either multiplying the cost by 1/3 or dividing by 3.

Step-by-step explanation:

(2((x+1) ^3 – (x+1) ^2 + (x+1)) )+3

Answers

( x + 1 )^3 = x^3 + 3x^2 +3x + 1;
(x + 1 )^2 = x^2 + 2x + 1;
=> (2((x+1) ^3 – (x+1) ^2 + (x+1)) )+3 =2( x^3 + 3x^2 +3x + 1 - x^2 -2x - 1 + x + 1 ) + 3 = 2( x^3 + 2x^2 + 2x + 1 ) + 3 =
= 2x^3 +4x^2 +4x + 5.
