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

Mathematics
1 answer:
spin [16.1K]3 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

Using the together rate, it is found that it will take 18 hours for Erick to build the garden box himself.

<h3>What is the together rate?</h3>

The together rate is given by the sum of each separate rate.

In this problem, the rates are given as follows:

  • Eric's: 1/x.
  • Drew's: 2/x.
  • Together: 1/6.

Hence:

\frac{1}{x} + \frac{2}{x} = \frac{1}{6}

\frac{3}{x} = \frac{1}{6}

x = 18.

Hence, it will take 18 hours for Erick to build the garden box himself.

Find each side length,round to the nearest tenth if necessary 11.
vagabundo [1.1K]

We can use a modified form of the Pythagorean Theorem to find the length of  x, also known as side b.

Pythagorean Theorem:

a^2 + b^2 = c^2

We can fill in the values of a^2 and c^2, and then solve for b.

14^2 + b^2 = 25^2

196 + b^2 = 625

Subtract 196 from both sides.

b^2 = 429

√ both sides.

b = 20.7

<h3>The value of x, or b, is equal to 20.7.</h3>

Your television has a height of 20 inches and a length of 21 inches. What is the length of the diagonal?
Liula [17]

Answer:

29

Step-by-step explanation:

You take the two sides and make them to the second power so 20 would be 400 and 21 would be 441. You add those numbers to get 841. Than the square root of 841 is the answer which is 29
