Answer:

  • \frac{4x^4 - 4x^2 - x - 3}{2x^2 - 3}

Step-by-step explanation:

<u>Step 1:</u>

  • Simplify: \frac{4x^4 - 4x^2 - x - 3}{2x^2 - 3}

<em>Checking for a perfect cube:</em>

  •  4x⁴ - 4x² - x - 3  is not a perfect cube.

<em>Trying to factor by pulling out:</em>

  •   Factoring:  4x⁴ - 4x² - x - 3
  • Thoughtfully split the expression at hand into groups, each group having two terms:
  • Group 1:  - x - 3
  • Group 2:  4x⁴ - 4x³
  • Pull out from each group separately:
  • Group 1:   (x + 3) • (-1)
  • Group 2:   (x² - 1) • (4x²)
  • Bad news!! Factoring by pulling out fails:
  • The groups have no common factor and can not be added up to form a multiplication

<em>Final result:</em>

  • <em />\frac{4x^4 - 4x^2 - x - 3}{2x^2 - 3}

The irrational numbers are: √8, √10 and √15

Step-by-step explanation:

A rational number is a number that can be written in the form p/q where p&q are integers and q≠0.

"All the numbers whose square root is not a whole number and has an infinite number of digits after decimal, are irrational numbers"

So in the given options

\sqrt{4} = 2

Which can be written in the required form so √4 is a rational number

\sqrt{8}=2.828427124746190097603.....

√8 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

\sqrt{10}=3.16227766016837933....

√10 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

\sqrt{15}=3.87298334620.....

√15 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

\sqrt{36} = 6

Which can be written in the required form so √36 is a rational number

Hence,

The irrational numbers are: √8, √10 and √15

Anna007 [38]
When you subtract and add what is in the parentheses you would get -15 so I’m guessing he didn’t go from left to right when working inside the parentheses but when you solve the whole problem out you would get the answer: -41.25 If I missed something or you need me to show the work just let me know but I hope this helps !
