Multiply. −3x^2−6x4+7x2 simplify your answer

Given expression is .

Now question says to simplify that.

To simplify, we can begin by combining like terms.

Like terms are those terms which contains same variable with equal exponent.

Here and contains same variable "x" with equal exponent "2". So that means they are like terms and we are allowed to combine their coefficients -3 and +7 which is -3+7=+4.

So the new expression will be

Now there are no more like terms that can be combined.

Hence final answer is

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
