☆1 arithmetic calculations
[1/1 Formula]
Work: Calculate the value of equation -1/2*(-sqrt(5)-1)^2-3/2*(-sqrt(5)-1)+2 .
Question type: Mathematical calculation
Solution:
-1/2*(-sqrt(5)-1)^2-3/2*(-sqrt(5)-1)+2
=-1/2*(-sqrt5-1)^2-3/2*(-sqrt(5)-1)+2
=-1/2*(-3.236068)^2-3/2*(-sqrt(5)-1)+2
=-1/2*(-3.236068)^2-3/2*(-sqrt5-1)+2
=-1/2*(-3.236068)^2-3/2*(-3.236068)+2
=-1/2*10.472136100623999-3/2*(-3.236068)+2
=-0.5*10.472136100623999-3/2*(-3.236068)+2
=(-5.236068)-3/2*(-3.236068)+2
=-5.236068-1.5*(-3.236068)+2
=-5.236068-(-4.854102)+2
=-0.381966+2
=1.618034
Answer:-1/2*(-sqrt(5)-1)^2-3/2*(-sqrt(5)-1)+2=1.618034
