Answer:

x^2 + {a/(a + b) + (a + b)/a}x + 1 = 0

Delta =  {a/(a + b) + (a + b)/a}^2 - 4

         =  {a/(a + b)}^2 + {(a + b)/a}^2 + 2 - 4

         =  {a/(a + b)}^2 + {(a + b)/a}^2  - 2

         =  {a/(a + b) - (a + b)/a}^2

If a is not equal to zero and a is not equal to -b => delta is always larger than 0

=>  Solution 1 =  - [ {a/(a + b) + (a + b)/a} + |{a/(a + b) - (a + b)/a}| ]/2

=>  Solution 2 = - [ {a/(a + b) + (a + b)/a} - |{a/(a + b) - (a + b)/a}| ]/2

Hope this helps!

Which inequality is equivalent to I x-4 I <9
Leni [432]

(B) –9 < x – 4 < 9 inequality is equivalent to Ix-4I <9.

<h3>What is inequality?</h3>
  • Inequality is a statement of an order relationship between two numbers or algebraic expressions (greater than, greater than, or equal to, less than, or less than or equal to).
  • Inequality is defined as a difference in size, amount, quality, social position, or another factor.
  • Inequality occurs when you have ten of something and someone else has none.
  • (mathematics) A statement stating that one quantity is less than (greater than) another.

So, Ix-4I <9:

  • |x-4|<9 ⇒ -9 < x-4 < 9
  • -5 < x < 13

Therefore, (B) –9 < x – 4 < 9 inequality is equivalent.
