Answer:
6x² + 5x - 2 = 0
Step-by-step explanation:
Given
2x² - 5x - 6 = 0 ← in standard form
with a = 2, b = - 5, c = - 6, then
sum of roots α + β = - =
product of roots = = - 3, then
sum of new roots = +
=
= = -
product of new roots = ×
= = -
Hence the required equation is
x² + x -
= 0 or
6x² + 5x - 2 = 0 ( multiplying through by 6 )

Also please note that it's everytime ^t/12 not (^t)/12
Step-by-step explanation:
Principal (P) = $2700
rate = 9%
t = ?
Amount =
Amount = 2700 +500 = $3200
So substituting all our values we get :
So we use log to solve for t :
Solving this using a calculator we get:
1.9714966193*12
