X^2=2x-x^2
2x^2-2x
2x(x-1)
x=1

v= D^2 akar D / 30 a^3 . phi
d=b^2-4ac
d= (-2)^2 - 4.2.0
d= 4

v= (4)^2 akar(4) / 30.(2)^3 . phi
v= 16.2 / 30.8 . phi
v= 32/240 . phi
v=0,13 phi atau 2/15 phi

mav kalo GJ, cz pake cara cpt
mv....gmbr kurva nya gimana? di jwbn nya adanya a.4 phi b.7/3phi c.phi d.11/15 e.1/3
