Tessellate S.T.E.M.S - Mathematics - School - Set 2 - Subjective Problem

For positive real numbers a,b,c,d,ea,b,c,d,e prove that (a3a+2)(b3b+2)(c3c+2)(d3d+2)(e3e+2)(S4S2+1)2(a^3-a+2)(b^3-b+2)(c^3-c+2)(d^3-d+2)(e^3-e+2) \geq \left( S_4- S_2 +1 \right)^2

where S4=abcd+abce+abde+acde+bcdeS2=ab+ac+ad+ae+bc+bd+be+cd+ce+deS_4 = abcd + abce + abde + acde + bcde \\ S_2 = ab+ac+ad+ae+bc+bd+be+cd+ce+de.
