Write the quadratic equation that has roots -1-rt2/3 and -1+rt2/3 if its coefficient with x^2 is equal to 1

weeeeeb [17]

The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9

<h3>How to determine the quadratic equation?</h3>

From the question, the given parameters are:

Roots = (-1 - √2)/3 and (-1 + √2)/3

The quadratic equation is then calculated as

f(x) = The products of (x - roots)

Substitute the known values in the above equation

So, we have the following equation

$f(x) = (x - \frac{-1-\sqrt{2}}{3})(x - \frac{-1+\sqrt{2}}{3})$

This gives

$f(x) = (x + \frac{1+\sqrt{2}}{3})(x + \frac{1-\sqrt{2}}{3})$

Evaluate the products

$f(x) = (x^2 + \frac{1+\sqrt{2}}{3}x + \frac{1-\sqrt{2}}{3}x + (\frac{1-\sqrt{2}}{3})(\frac{1+\sqrt{2}}{3})$

Evaluate the like terms

$f(x) = x^2 + \frac{2}{3}x - \frac{1}{9}$

So, we have

f(x) = x²+ 2/3x - 1/9

Please help me!

Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

$(\frac{2}{3}s + \frac{5}{6}s) = 21$
$(\frac{4}{6}s + \frac{5}{6}s) = 21$
$\frac{9}{6}s = 21$
$\frac{3}{2}s=21$

Step 2: Multiply both sides by 2/3.

$\frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}$
$s = \frac{42}{3}$
$s = 14$
