You can put this solution on YOUR website!
This is not an equation, so you won't solve it, but you can simplify it
:
2y%5E5%28y%5E2-4y%29%2B9y%5E7
distribute, removing the brackets, {add exponents)
2y%5E7-8y%5E6+%2B+9y%5E7
Add like terms
2y%5E7+%2B+9y%5E7+-+8y%5E6
11y%5E7-8y%5E6
Factor out y^6
y%5E6%2811y-8%29
