у (х + 3) + z (x + 3) = (y + z)(x + 3)
(32а^4-24а^3):(8а^2)-12а^4:(6а^2)=
1) (32а^4-24а^3)= 8а^3(4а-3)
2) 8а^3(4а-3)/8а^2= а(4а-3)
3) 12а^4:6а^2= 2а^2
4) а(4а-3)-2а^2= 4а^2-3а-2а^2=2а^2-3а= а(2а-3)
Ответ: а(2а-3)
8*(-5.5)-11*(-4)=-44+44=0
F'(x)=(1/2) * (1/(√(-3x²+6x+4))) * (-6x+6) = (-3x+3) / (√(-3x²+6x+4))
f'(2) = (-3*2+3) / (√(-3*2²+6*2+4))=(-3)/(√(4))=-3/2=-1.5
