What is the exact value of the other root?
Lostsunrise [7]

The exact value of the other root to the quadratic equation is x = -2 - \sqrt 6

<h3>How to express the solution?</h3>

One of the root is given as:

x = -2 - \sqrt 6

As a general rule, the solution to a quadratic equation is represented by:

x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}

This means that the actual root of the given root is:

x = -2 \pm \sqrt 6

Split the equation

x = -2 - \sqrt 6 and x = -2 + \sqrt 6

Hence, the exact value of the other root to the quadratic equation is x = -2 - \sqrt 6

Show the work please
igor_vitrenko [27]

Answer:

10/11

Step-by-step explanation:

At first we have to swap the fractions to make those fractions into a normal number. Because it will become a multiplication.

4 × (x + 5) < 5 × (3x + 2)

We will multiply the numbers by the brackets.

4x + 20 < 15x + 10

Now we swap the constant and values from left to right side.

4x - 15x < 10 - 20

or, - 11x < -10

If we divide the inequality by a negative number, say - 11, the inequality becomes reverse.

Therefore,

[-11x ÷ (-11)] > [(-10) ÷ (-11)]

or, x > (10/11)
