Why is

(1 + x)^{2}

less accurate than

(x + 2) x + 1

for small

x

https://math.stackexchange.com/questions/499159/why-is-1x2-less-accurate-than-x2x1-for-small-x

Let's us assume that

x \approx 1 0^{- (n - k)}

, where

n

is the number of significant digits remembered (in double arithmetic, this is roughly

16

) and

k

is a small positive integer. Now, compare:

1 + x

How do you solve and graph

- 9 \leq 2 x - 5

and

2 x + 1 < 5

https://socratic.org/questions/how-do-you-solve-and-graph-9-2x-5-and-2x-1-5

solve:

- 2 \leq x < 2

graph (reds):

- - - - - ((- 2) - - 0 - -) 2 - - - - - - - \to x

Explanation:

- 9 \leq 2 x - 5

2 x + 1 < 5

2x+1=1 One solution was found : x = 0 Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : ...

What is the property that allows

5^{2 x + 1} = 5^{2}

to become

2 x + 1 = 2

https://math.stackexchange.com/questions/336133/what-is-the-property-that-allows-52x1-52-to-become-2x1-2

Its a really good question, the thing is that

5^{x}

is injective, so that it is only possible that

5^{x} = 5^{y}

when

x = y

. You know that

a^{b} \cdot a^{c} = a^{b + c}

, so when you divide by

5^{y}

we ...

How do I check to see if the solution is 1 for the equation

2 x + 1 = 3

https://socratic.org/questions/how-do-you-combine-like-terms

Manish Bhardwaj Nov 16, 2014 If the solution of the equation is 1, it means that x= 1 will make the two sides equal. 2x + 1 = 3 2.1 + 1 = 3 2 + 1 = 3 3 = 3 x is the solution of the ...
