Question

Simplify the following expression.
2x - 10y + 3x2 + 7y - 10x.

Answer 1

\(2x-10x=-8x\) since \(2-10=-8\)
what is \(7y-10y\) ?

Answer 2

3y @satellite73

Answer 3

close

Answer 4

\(7-10=-3\) though, not \(3\)

Answer 5

@satellite73 oh..

Answer 6

so you have
\[2x-10x=-8x\\7y-10y=-3y\] and \(3x^2\) just hanging out by itself
final answer will be
\[3x^2-8x-3y\] in any order you choose

Answer 7

@satellite73 thank you!
