Question

a⁴+b⁴-6ab,b⁴-2ab⁴+8ab-7a⁴+3ab​

Answer 1

Answer: let 2-x =a 3-x =b Given a⁴ +b⁴ =(a+b)⁴ Expansion via binomial on RHS a⁴ +b⁴ = a⁴+b⁴ +4a³b+ 4ab³ + 6a²b² therefore ab(4a²+4b²+6ab)=0 therefore ab*(2a²+3ab+2b²)=0 Since discriminant of the quadratic in bracket is <0 Only 2a²+3ab+2b² can't be zero (divide by b² to make quadratic) Hence Soln…
