Work: Calculate the value of equation ((3+sqrt5)/2)^2+3*(3-sqrt5)/2*3-3 .
Question type: Mathematical calculation
Solution:
((3+sqrt5)/2)^2+3*(3-sqrt5)/2*3-3
=(5.236068/2)^2+3*(3-sqrt5)/2*3-3
=2.618034^2+3*(3-sqrt5)/2*3-3
=2.618034^2+3*0.763932/2*3-3
=6.854102025156001+3*0.763932/2*3-3
=6.854102025156001+2.291796/2*3-3
=6.854102025156001+1.145898*3-3
=6.854102025156001+3.437694-3
=10.291796-3
=7.291796
Answer:((3+sqrt5)/2)^2+3*(3-sqrt5)/2*3-3=7.291796
