Find quadratic equation who's roots are 1/2 and -1/3​

Mathematics
1 answer:
spin [16.1K]2 years ago
8 0

Answer:

Let's say you have the factored quadratic (x-5)^2=0. The root is just 5, because when you set x-5 to zero and solve for x you have 5. In the same way, we can factor the equation as (x-1/2)(x+1/3), because if you set x-1/2=0 the solution is 1/2. The x+1/3 can also be set to zero and you get -1/3 . Therefore the quadratic has to be (x-1/2)(x+1/3).Foiling this out you get x^2-1/6x-1/6. Note we have to set this equal to zero like the first equation, so the answer is x^2-1/6x-1/6=0

Drag steps of the solution into order to solve for x in the equation 9(x + 3) = 108.
Marat540 [252]

Answer:

Given expression is,

9(x+3) = 108

In solving the equation the steps are as follows,

Step 1 : 9x + 27 = 108      ( By distributive property )

Step 2 : 9x = 81               ( Subtracting 108 on both sides )

Step 3 : x = 9                   ( Divide both sides by 9)

Hence, by the above explanation we can drag the steps of solution in correct order.

36 and 38<br><br>Steps and explaination please
elena55 [62]

Answer:

36.   Limit = 2/3.

Step-by-step explanation:

36.

(∛ x- 1)  / (√x - 1)

Rationalise the expression:-

Multiply top and bottom by (√x + 1):-

(∛x - 1)(√x + 1) /  (√x - 1)(√x + 1)

=  x^5/6  + ∛x - √x - 1 /  (x - 1)

Applying L'hopital's rule ( differentiating top and bottom of the fraction) we have:

Limit as x ----> 1 of  [5/6 x^-1/6 + 1/3 x^(-2/3)  - 1/2x^-1/2] / 1

= 5/6(1) + 1/3(1) - 1/2(1)  =  2/3  (answer).

What i
shusha [124]

Answer:

Answer: B, 6/11

Step-by-step explanation:

<em>Well we know that 3+2+1=6+3=9.</em>

<em>So that means we will add the 2 brown crayons to the denominator.</em>

<em>The denominator before we added 2 to it, it was 9 as a common denominator. If we want to get the common numerator we are going to have to add the top and that will become 9 then you will have to subtract that by 3</em>

<em>6/11 is also the smallest number that you can get.</em>

<em>You can turn the fraction into a decimal and have it that way to make it easier.</em>

<em>When you turn a fraction into a decimal the number is always the same but with comparing numbers it is a lot easier to do than comparing fractions</em>

Hope this helps, and if it did I would appreciate it if you marked me as Brainllest. Have a wonderful day!
