Question

The degree of 2a2 - b2 + 7a2b - 1

Answer 1

Answer:

degree:a =2,b=2,a=2b=1

Answer 2

Given,

$\[2{a^2} - {b^2} + 7{a^2}b - 1\]$

Solution,

Know that the degree of a polynomial is the highest power of the variables.

Power of first term,

$\[ = 2\]$

Power of second term,

$\[ = 2\]$

Power of third term,

$\[\begin{array}{l} = 2 + 1\\ = 3\end{array}\]$

Power of fourth term,

$\[ = 0\]$

Highest power $\[ = 3\]$

Hence the degree of given equation is 3.
