Solve for x in each of the following quadratic equations.
Eduardwww [97]
Okay so...
x² = 5x + 24          move it, so one side equals zero.
 x² - 5x - 24 =0    factors of 24 is 3 and 8 when you subtract 8 from 3 you get -5.
(x+3)(x-8)
x+3= 0    or    x-8=0       
x= -3       or    x=8

b. 2x² - 5x + 1=0
 quadratic formula = -b +-√b²-4ac / 2a
a= 2 b= -5 c=1
-(-5) +-√(-5)² - 4(2)(1) / 2(2)

5+-√25 - 8 / 4
   =5 +- √17 / 4

x= 5/4 + √17 / 4   or    x= 5/4 - √17/4

i couldn't find the plus-minus sign that why there's (+-)
i hope this helps!   :)

Emily reads a story book. o the first day, she reads 1/9 of the whole book, and on the second day, she reads 24 pages. The ratio
Marina86 [1]

There are 270 pages in this book.

Given that,

Emily reads a storybook the first day,

She reads 1/9 of the whole book, and on the second day, she reads 24 pages.

The ratio of the number of pages read to the remaining pages in the two days is 1:4.

We have to find

How many pages are there in this book?

According to the question,

Let, P is the number of pages,

The first day Emily reads p/9 pages of the whole book,

And the second day she read 24 pages.

The ratio of the number of pages read to the remaining pages in the two days = 1;4 = p/5.

Therefore,

The number of pages reads first day + the number of pages read the second day = The ratio of the number of pages read to the remaining pages in the two days

\rm \dfrac{p}{9} + 24 = \dfrac{p}{5}\\\\ \dfrac{p}{5} - \dfrac{p}{9} = 24\\\\\dfrac{p \times 9 - p\times 5}{45} = 24\\\\ \dfrac{9p-5p}{45} = 24\\\\\dfrac{4p}{45} = 24\\\\4p = 24\times 45\\\\4p = 1080\\\\p = \dfrac{1080}{4}\\\\p = 270 \ pages

Hence, there are 270 pages in this book.
