Question

what is the coefficient of y2 in the expression 2x2y -10xy2 + 5y2


​

Answer 1

Answer:

5 is the coefficient of y2

Answer 2

Given,

the expression $2x2y - 10xy^{2}+5y^{2}$

To Find,

the coefficient of $y^{2}$

Solution,

the expression given is  $2x2y - 10xy^{2}+5y^{2}$

the terms in this expression that contains $y^{2}$ are,

$10xy^{2},5y^{2}$

now, the coefficient of $10xy^{2}$ is 10x

and the coefficient of $5y^{2}$ is 5.

Hence 10x and 5 are the coefficient of y² in the given expression.
