4 x^{2} -11x-3=0
(4x+1)(x-3)=0
We can solve for x by setting each parentheses equal to 0

4x² - 11x = 3
4x² - 11x - 3 = 0
4x² -12x + x - 3 = 0
4x (x - 3) + 1(x - 3) = 0
(x - 3) (4x + 1) = 0
Using zero product property,
Either,
     x - 3 = 0
          x = 3
Or,
     4x + 1 = 0
           4x = -1
             x = -1/4

Allushta [10]

Answer:

<h2>  $24</h2>

Step-by-step explanation:

The question is not complete, here is the complete question

"<em>DeMarkus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48, what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?"</em>

<h2 /><h2>Solution</h2><h2>Take note of the words "of" and "off" </h2>

1/4 of $48= 0.25*48=$12

so he thought he should pay $12

1/4 off $48= $48-$12= $36

now the difference is

36-12= $24
