Which is a solution of x2 – x – StartFraction 3 Over 4 EndFraction = 0?

x = - , x =

Step-by-step explanation:

Given

x² - x - = 0 ( add to both sides )

x² - x =

Solve using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2( - )x + = +

(x - )² = 1 ( take the square root of both sides )

x - = ± 1 ( add to both sides )

x = ± 1

Thus

x = - 1 = -

x = + 1 =

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
