Solve 2x2 + x − 4 = 0.<br><br><br> x^2 + ____x+____ = 0

alisha [4.7K]

Kate: Please, for clarity, use " ^ " to denote exponentiation: 2x^2 + x − 4 = 0

And please include the instructions.

2x^2 + x − 4 = 0 can be re-written: 2(x^2 + (1/2)x - 2) = 0

Dividing both sides by 2 results in x^2 + (1/2)x - 2 = 0

Let's "complete the square:" x^2 + (1/2)x + (1/4)^2 - (1/4)^2 = 0

Then (x+(1/4))^2 = (1/4)^2

Taking the sqrt of both sides: x+1/4 = plus or minus 1/4

Solving for x: x = -1/4 plus or minus 1/4

Solving for x (continued): x = 0 and x = -1/2

$\mathrm {Hey, there!}$

Let's solve your problem:

The answer would be 280%.

We know the following information:

2pm - 15 toilet paper rolls

5pm - 57 toilet paper rolls

We have to find the <u>percent rate of change.</u>

Here is how we will do this problem:

<h3><u>First, Set up a ratio:</u></h3>

Change in the quantity [15 - 57]

-------------------------------------

Original quantity [15]

57 - 15 = 42

<h3><u>Next, we will divide. the ratio.</u></h3>

Given quantity - 42

Number of packs sold at 2pm - 15

Fraction - 42/15

<h3><u>Convert the fraction to a decimal.</u></h3>

Fraction - 42/15

Decimal - 2.8

<h3><u>Make the decimal to a percent.</u></h3>

Decimal - 2.8

Percent - 28%

<h2><u>Our answer is 280%</u></h2>
