================================
Solution and Answer for No.1
[tex]\large\:Simplify: \\3 {x}^{3} y + 3x {y}^{2} - 4 {y}^{3} \\ = 3 {x}^{3}y + 3x {y}^{2} + ( - 4) {y}^{3} [/tex][tex]\large\: Apply \: rule: \: \\ = ( - a) = - a \\ = ( - 4) - - 4 [/tex]
Hence the answer is:
[tex] \huge\rm{3x³+\:3xy²\:-4y³}\ [/tex]
=============================
Solution and Answer for No.2
[tex] \large\rm{Simplify:}\ [/tex]
[tex] \large\rm{5zt²-2zt²}\ [/tex]
Since they have the same element, we can subtract directly, therefore:
[tex] \large\rm{5zt²-2zt²=3zt²}\ [/tex]
Hence, the answer is:
[tex] \huge\rm{3zt²}\ [/tex]
