Answer:
9/11
Step-by-step explanation:
[(3 - 2√5) / (3 - 2√5)][(3 - √5) / (3 + 2√5)] = a√5 - 19/11
[(3 - 2√5)(3 - √5) / (3 - 2√5)(3 + 2√5)] = a√5 - 19/11
(9 - 3√5 - 6√5 + 2 * 5) / (9 + 6√5 - 6√5 - 4 * 5) = a√5 - 19/11
(19 - 9√5) / -11 = a√5 - 19/11
(-19/11) + (-9√5 / -11) = a√5 - 19/11
9√5/11 - 19/11 = a√5 - 19/11
a = 9/11
