The coefficient of the term with the power of 2: 4y+3y^2 + y + 2 is equal to 3
<u>Solution:</u>
Given, expression is
It can be simplified and written as
We have to find the coefficient of the term with the power of 2.
Now, we know that, coefficient is factor by which the term is being multiplied with.
So, now, let us find the term with power 2 and then we can find by which factor it is being multiplied.
If we observe, is the term with power 2.
And, it is being multiplied by 3.
Hence, the coefficient of term with power 2 is 3.
