Simplify the following expression:

2x - 4y + 3x2 + 7y - 16x

3x^2-14x+3y (if you didn't know, "^2" means that its an exponent)

Step-by-step explanation:

Let's simplify step-by-step.

2x-4y+3x^2+7y-16x

=2x+-4y+3x^2+7y+-16x

Combine Like Terms:

=2x+-4y+3x^2+7y+-16x

= (3x^2) + (2x+-16x) + (-4y+7y)

=3x^2+-14x+3y
