How do you factor quadratics trinomials

You can factor trinomials by taking factors of the lead term (x^2) and using them in the front of a set of parenthesis. For instance, if you had 2x^2 as the first term, you would use (2x )(x).

Now to find what goes at the end of the parenthesis, you take factors of the last number. Say our last number was -5, we could use -5 and 1 or 5 and -1. For the purpose of this, we'll use -5 and 1. This would give us (2x - 5)(x + 1).

Now, to be sure you've selected the right ones, you would multiply the two parenthesis together and see if the middle term matches the original equation.

(2x - 5)(x + 1)

2x^2 - 5x + 2x - 5

2x^2 - 3x - 5

So you'll notice that the middle term is -3. If this wasn't the original, you could try those numbers in a different order until you get the correct middle term.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
