The $2 bill has Thomas Jefferson on the front of it write an expression to find out how much money v bills with Thomas Jefferson on them would be worth?

Step-by-step explanation:

Well, I really don’t like graphic approaches in math, so hear ya go a formula:

Although there are easier ways that work for some quadratics, but this formula works for them all. (It is atached, have a look)

So,

( -(-2)+- square root of ((-2)^2-4(1)(-40)) ) / 2(1)

Note that for a hear I use one, since there is nothing in front of x.

( 2 + (12.8) ) / 2 < with plus

( 2 -(12.8) ) / 2 < with minus

X = 7.4

Or

X = -5.4

(Quad equations have 2 answers)
