2xsquared +3x+1=0 solve using quadratic formula

Mathematics
1 answer:
vlada-n [284]3 years ago
5 0

Answer:

<em>x</em> = \frac{1}{2} , -1

Step-by-step explanation:

The quadratic formula is:  <u>-b±√b²-4ac</u>

                                                 2a

The discriminant (Δ) is b²-4ac. Evaluating this expression after substituting for <em>a, b </em>and <em>c</em> helps you identify the number of real solutions to the quadratic equation.

<em>a </em>= 2, <em>b</em> = 3, <em>c </em>= 1

Δ = -3²- 4 x 2 x 1;

Δ = 1

<u>-3±1 </u>

The net profit or income for case A and case B based on the information will be $9250 and $9500 respectively.

<h3>How to compute the net profit?</h3>

Case A:

Based on the information, the price of fertilizer will be:

= 0.25 × 100 × 50

= $1250

Price of wheat = 3.50 × 50 × 50

= $10500

Net profit = $10500 - $1250

= $9250

Case B:

Price of fertilizer will be:

= 0.50 × 70 × 50

= $1750

Price of wheat = 4.50 × 50 × 50

= $11250

Net profit = $11250 - $1750

= $9500

Therefore, the net profit or income for case A and case B based on the information will be $9250 and $9500 respectively.
