Which of the following are solutions to the equation below?

scoundrel [369]

Answer:

The correct options for the solution values are:

$x=2\sqrt{2}-5$

$x=-2\sqrt{2}-5$

Step-by-step explanation:

Given the expression

$x^2+10x+25=8$

Subtract 25 from both sides

$x^2+10x+25-25=8-25$

Simplify

$x^2+10x=-17$

Add 25 or 5² to both sides

$x^2+10x+5^2=8$

$x^2+10x+5^2=\left(x+5\right)^2$

so the expression becomes

$\left(x+5\right)^2=8$

$\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}$

solve

$x+5=\sqrt{8}$

Subtract 5 from both sides

$x+5-5=2\sqrt{2}-5$

$x=2\sqrt{2}-5$

solve

$x+5=-\sqrt{8}$

Subtract 5 from both sides

$x+5-5=-2\sqrt{2}-5$

$x=-2\sqrt{2}-5$

Therefore, the solution to the equation

$x=2\sqrt{2}-5,\:x=-2\sqrt{2}-5$

Hence, the correct options for the solution values are:

$x=2\sqrt{2}-5$

$x=-2\sqrt{2}-5$

PLEASE HELP!!20 pts question

value of x is x=2, x=-2 and x=0

Step-by-step explanation:

Let a = x^2+4. Use a to find the solution for the following equation:

$(x^2+4)^2+32=12x^2+48$

Solving

$(x^2+4)^2+32=12x^2+48$

Taking 12 common from LHS

$(x^2+4)^2+32=12(x^2+4)$

Let a=x^2+4

$(a)^2+32=12(a)\\a^2+32=12a\\a^2-12a+32=0$

Factoring the equation

$a^2-8a-4a+32=0\\a(a-8)-4(a-8)=0\\(a-8)(a-4)=0\\a-8=0\,\,and\,\,a-4=0\\a=8\,\,and\,\,a=4\\$

Putting value of a i.e x^2+4

$x^2+4=8\,\,and\,\,x^2+4=4\\x^2=8-4\,\,and\,\,x^2=4-4\\x^2=4\,\,and\,\,x^2=0\\Taking\,\,square\,\,root\,\,at:\\x=\pm 2\,\,and\,\,x=0\\$

So, value of x is x=2, x=-2 and x=0

Which number produces an irrational number when added to 1/3

Nataly [62]

Answer:

An irrational number produces an irrational when added to

Step by step explanation:

To find : What number produces an irrational when added to ?

Solution :

We know that,

It is a rational number as it is repeating.

So, If we add a rational number into a rational number it always gives you a rational number.

To produce an irrational number,

If we add an irrational number to a rational number it always gives you an irrational number.

For example :

An irrational number -

A rational number -

Adding these two number,

This number is non-terminating and non-repeating.

Therefore, An irrational number produces an irrational when added to

dome.
