Question

Simplify (5x³y²-4y³+6x²)+(7x²y³+2x²-x³y³)

Answer 1

Answer:

Let  

(

5

x

3

y

2

−

4

y

3

+

6

x

)

+

(

7

x

2

y

3

−

x

3

y

3

)

.

We add similar terms, that is,  

6

x

2

and  

2

x

2

. Thus we have

5

3

y

2

+

7

x

2

y

3

−

x

3

y

+

8

x

2

.

By taking the common factor  

x

2

y

2

between the first three terms we obtain
