What is the solution to x4 - 12x2+10>0

Mathematics
1 answer:
alexira [117]4 years ago
5 0

Answer:

  (-√(6-√26) < x < √(6-√26)) ∪ (x < -√(6 +√26)) ∪ (√(6 +√26) < x)

Step-by-step explanation:

Using x^2 = z, the equation can be rewritten as ...

  z^2 -12z +10 > 0

  (z -6)^2 -26 > 0

  |z -6| > √26

This resolves to two equations.

This one ...

  x^2 -6 < -√26 . . . . substitute x^2 for z

  |x| < √(6-√26) . . . . add 6, take the square root; use √a^2 = |a|

  -√(6-√26) < x < √(6-√26)

__

and this one ...

  x^2 -6 > √26

  |x| > √(6 +√26)

  x < -√(6 +√26) ∪ √(6 +√26) < x

maeve likes to make her salads in advance she made 15 salads for 3 days how many salads does she eat per day unit rate
Tju [1.3M]

The number of salads Maeve eats per day if she made 15 salads for 3 days is 5 salads eaten per day.

<h3>Unit rate</h3>

Unit rate refers to the number of units of the first type of quantity corresponding to one unit of the second type of quantity.

  • Number of salads = 15 salads
  • Number of days = 3 days

Unit rate of salad eaten per day = Number of salads ÷ Number of days

= 15 ÷ 3

= 5 salads eaten per day

A salad is a food made primarily of a mixture of raw or cold ingredients, typically vegetables, usually served with a dressing such as vinegar or mayonnaise.

Therefore, the number of salads Maeve eats per day if she made 15 salads for 3 days is 5 salads eaten per day.
