Regardless of the sign of
, we have
(never negative). But multiplying by -1 makes it negative.
On the other hand,
which can never be negative for real
.
Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a
a = 10
b = -1
c = 9
1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)
1 +/- sqrt(1 - 360) / 20
x = 1 +/- sqrt(359i) / 20
Hope this helps!
3m + 2n= p solve for n
subtract 3m on both sides
2n = p - 3m
divide both sides by 2
n = p/2 - 3m/2
-----------------------
xy - 5 = k solve for x
add 5 on both sides
xy = k + 5
divide both sides by y
x = k/y - 5/y
15000 * (1+ 0.03)^4
15000 *1.1255 = 16882.63 total after 4 years
16882.63 - 15000 = 1882.63 total interest
