Write coefficient of b in 9b^3 - a - 6ab
I want to say -6a but I suspect that's not what you had in mind.
Yeah I feel it should be 6ab^2
Actually my question was to find coefficient of b from 9b^3.
To find the coefficient of b in the expression 9b^3 - a - 6ab, we need to identify the terms that involve b and determine their corresponding coefficients.
The given expression contains three terms:
1. 9b^3
2. -a
3. -6ab
Let's analyze each term:
1. In the term 9b^3, the coefficient of b is 9. The exponent of b is 3, but the coefficient refers to the numerical part in front of the variable. Therefore, the coefficient of b in the term 9b^3 is 9.
2. In the term -a, there is no b present, so the coefficient of b is 0.
3. In the term -6ab, the coefficient of b is -6. Again, the coefficient refers to the numerical part in front of the variable, and in this case, it is -6.
Therefore, the coefficients of b in the given expression are 9 and -6.
