Question

If (x^2 y + y^2 + 3) is subtracted from (3x^2 y + 2 y^2 + 5), then coefficient of y in the result is ________


fasssttt my exam is going on ​

Answer 1

Answer:

Coefficient of y is 2 be because coefficient means the numerical value attached to the variable

Answer 2

$\rm{\left(3 x^{2} y+2 y^{2}+5\right)-\left(x^{2} y+y^{2}+3\right)}$

$\longrightarrow\rm{3 x^{2} y+2 y^{2}+5-\left(x^{2} y+y^{2}+3\right)}$

$\longrightarrow\rm{3 x^{2} y+2 y^{2}+5-x^{2} y-y^{2}-3}$

$\longrightarrow\rm{3 x^{2} y-x^{2} y+2 y^{2}-y^{2}+5-3}$

$\longrightarrow\rm{2x^{2} y+y^{2}+2}$

A number used to multiply a variable is known as coefficient. In our result, We have $\rm{2x^2}$ as coefficient for $\rm{y}$. Hence the Required answer is : $\rm{2x^2}$
