Question

Subtract (2x2 – xy + y2

) from (9x2 – y

2 + 11xy )​

Answer 1

Answer:

Step-by-step explanation:

First, adding 3x  

2

+5xy+7y  

2

+3 and 2x  

2

−4xy−3y  

2

+7, we have  

= 3x  

2

+5xy+7y  

2

+3+2x  

2

−4xy−3y  

2

+7  

= 5x  

2

+xy+4y  

2

+10  

Now,  

Subtracting 5x  

2

+xy+4y  

2

+10 from 9x  

2

−8xy+11y  

2

 

= (9x  

2

−8xy+11y  

2

)−(5x  

2

+xy+4y  

2

+10)  

= 9x  

2

−8xy+11y  

2

−5x  

2

−xy−4y  

2

−10  

= 4x  

2

−9xy+7y  

2

−10
