degree of 9. It has 3 terms and a degree of 10. It has 4 terms and a degree of 9. It has 4 terms and a degree of 10.
1 answer:
Answer: The polynomial has 3 terms and a degree of 10.
Step-by-step explanation:
The given polynomial: 
Here, two terms
and
have same power for s and t i.e. they are like terms.
Combine like terms , we get
i.e. there are 3 terms.
Degree of
is 1+9=10;
Degree of
is 6+2=8;
Degree of
is 7.
Since degree of the polynomial = highest degree i.e. 10
Hence, the polynomial has 3 terms and a degree of 10.

Answer:
2500
Step-by-step explanation:
a² + 2ab + b²
49² + 98 + 1
Comparing terms
a²= 49²
a= 49
2ab = 98
2× 49 × b = 98
98b = 98
b= 98/98
b = 1
or
b²= 1
b=√1
b= 1
a=49 and b= 1
Hence (a+b)²= (49+1)²
50²= 2500
