Answer:

You cant find that out. X and Y are like two different animals in a zoo, and XY is a whole other animal, you cant combine two animals in the same cage, so X and Y cant turn into XY. You could do:

ELEN [110]

Answer:

  • a = 5, b = -1

Step-by-step explanation:

Simplify the left side.

<u>Multiply both numerator and denominator by the conjugate of the denominator:</u>

  • (√3 - 1)/(√3 + 1) =
  • (√3 - 1)(√3 - 1)/(√3 - 1)(√3 + 1) =
  • (√3² - 2√3 + 1)/(3 - 1) =
  • (10 - 2√3)/2 =
  • 5 - √3

<u>Compare this to the right side to get:</u>

  • 5 - √3 = a + b√3
  • a = 5, b = -1
