3x² = 2(2x+1)


Expand the brackets

3x² = 4x + 2


Rearrange

3x² - 4x - 2 = 0


Quadratic formula is

(-b ± √(b² - 4ac)) / 2a


Where

a = 3
b = -4
c = -2


Therefore, putting these values in to the quadratic formula:

x = 15.487
or
x = -3.487

Round the answers how you will.

Step 1: Make equation equal to Zero

3x^2 = 4x + 2


3x^2 - 4x - 2 


Step 2: use equation

a= 3 b = -4 c= -2 

after plugging in answer should be

(2 + or - sqrt 10) / 3

A function assigns the value of each element of one set to the other specific element of another set. The total amount of credit cards opened at the two locations is given as 45+3t.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given that the number of credit cards, A, that is opened t months since January can be modeled by the function A(t) = 20 + 4t, while the number of credit cards opened at another location, B, is defined by the function B(t)=25−t.

Now, the total number of credit cards that are opened at both the location together will be,

Total number of credit cards = A(t) + B(t)

                                                = 20 + 4t + 25 - t

                                                = 20 + 25 + 4t - t

                                                = 45 + 3t

Hence, the total amount of credit cards opened at the two locations is given as 45+3t.
