Answer 1

Answer:

a swer please mark ne brainliest and follow me

Step-by-step explanation:

Given :-

\rm(7xy + 5yz - 3zx), (4yz + 9zx - 4y) , ({ - 3x}^{2} + 5x - 2xy)(7xy+5yz−3zx),(4yz+9zx−4y),(−3x

2

+5x−2xy)

》To do :-

Addition of (given) terms

》Solution :-

\begin{gathered}\dag \: \: \: \: \: \: \sf \small{7xy + 5yz - 3zx + 4yz + 9zx - 4y + ( { - 3x}^{2} + 5x - 2xy)} \\ = > \small \sf7xy - 2xy+ 5yz +4yz - 3zx + 9zx - 4y + 5x +( { - 3x}^{2} ) \\ = > \underline{ \: \small \sf5xy + 9yz + 6xz - 4y + 5x - {3 {x}^{2} }^{} \: }\end{gathered}

†7xy+5yz−3zx+4yz+9zx−4y+(−3x

2

+5x−2xy)

=>7xy−2xy+5yz+4yz−3zx+9zx−4y+5x+(−3x

2

)

=>

5xy+9yz+6xz−4y+5x−3x

2

Hence, Required Value of operation done above,

\sf5xy + 9yz + 6xz - 4y + 5x - {3 {x}^{2} }^{}5xy+9yz+6xz−4y+5x−3x
