Answer:
x=1+/-4i
Step-by-step explanation:
(x+1)/3-(2x-1)/x=-1
find the common denominator,
in this case, it's going to be 3x.
(x^2+x)/3x-(6x-3)/3x=-1
(x^2+x-6x+3)/3x=-1
x^2-5x+3=-3x
x^2-5x-(-3x)+3=0
x^2-5x+3x+3=0
x^2-2x+3=0
apply the quadratic formula in order to find the roots for x.
Since ax^2+bx+c=0, in this case,
a=1, b=-2, c=3
--------------------------
x=(-b+/-sqrt(b^2-4ac))/2a
x=(2+/-sqrt(4-12))/2
x=(2+/-8i)/2
x=1+/-4i
So far, Jackie has read 217 pages
In order to determine the total number of pages Jackie read, we would have to determine the number of pages she read each day and add these pages together
- Number of pages she read on Monday =
x 252 = 126 pages - Number of pages she read on Tuesday = 28 pages
- Number of pages she read on Wednesday =
x 252 = 63 pages
The total number of pages she has read so far = 126 + 28 + 63 = 217 pages
