What are the solution of the equation x^2- 4x -32 = 0 ?show your work and justify each step.
soldier1979 [14.2K]
X^2-4x-32=0

(x+a)(x+b)

x^2-(a+b)x+ab

a+b=4
ab=-32

a=-b+4
(-b+4)b=-32

-b^2+4b=-32
b^2-4b-32=0
b=8,-4

If b=8, a=-4
If b=-4, a= 8

Plug in a and b to (x+a)(x+b)
x= -4, 8

ermaine’s father owes $6,300 in interest at the end of a 60-month car loan at a 7% simple annual interest rate. What was the ori
Aleks04 [339]

The pertinent formula is i = p*r*t.  Here, i = $6,300, r = 0.07 and t = 5 yrs.

We want to solve this for the principal, p.  Since i = p*r*t,  p = i / (rt).  In this case, the principal was:

p = $6,300 / [0.07*5] = $6,300 / 0.35 = $18,000
