group and factor/undistribute
(x^2y^3-2y^3)+(-2x^2+4) (y^3)(x^2-2)+(-2)(x^2-2) see the (x^2-2) is common term so undistribute (x^2-2)(y^2-2)

Write this in y=ax^2+b form:
y=(x-5)^2 - 2
Answers
Expand (x - 5)^2
(x - 5)^2 = (x - 5)(x - 5)
Multiply all the terms in the first parenthesis to all the terms in the 2nd:
x * x = x^2 x * -5 = -5x -5 * x = -5x -5 * -5 = 25
So we have:
x^2 - 5x - 5x + 25
Combine like terms:
x^2 - 10x + 25
Plug it back in:
y = (x - 5)^2 - 2
y = x^2 - 10x + 25 - 2
Combine like terms:
y = x^2 - 10x + 23

You use 6 gallons of water on 20 plants in your garden. At that rate, how much water will it take to water 30 plants?
Answers
9 because if you split the planta up into 10's, you would split the gallons into 3's. Thats 3 gallons per 10 plants
To do this, set up a proportion. The proportion would be 6/20=x/30. To do this, multiply 30 by 6. This gives you 180. Now you want to divide 180 by 20. This gives you 9. It would take 9 gallons of water to water 30 plants.
