Step-by-step Solution
To find a quadratic equation with the given roots \( -4 \pm \sqrt{10} \), we can use the fact that if \( r_1 \) and \( r_2 \) are the roots of the quadratic equation, then the equation can be expressed in the form:
\[
x^2 - (r_1 + r_2)x + (r_1 \cdot r_2) = 0
\]
First, we identify the roots:
- \( r_1 = -4 + \sqrt{10} \)
- \( r_2 = -4 - \sqrt{10} \)
Next, we calculate the sum of the roots \( r_1 + r_2 \):
\[
r_1 + r_2 = (-4 + \sqrt{10}) + (-4 - \sqrt{10}) = -8
\]
Now, we calculate the product of the roots \( r_1 \cdot r_2 \):
\[
r_1 \cdot r_2 = (-4 + \sqrt{10})(-4 - \sqrt{10}) = (-4)^2 - (\sqrt{10})^2 = 16 - 10 = 6
\]
Now we can substitute these values into the quadratic equation form:
\[
x^2 - (r_1 + r_2)x + (r_1 \cdot r_2) = 0
\]
Substituting the values we found:
\[
x^2 - (-8)x + 6 = 0
\]
This simplifies to:
\[
x^2 + 8x + 6 = 0
\]
Thus, the quadratic equation in the form \( x^2 + bx + c = 0 \) is:
\[
\boxed{x^2 + 8x + 6 = 0}
\]
Quick Answer
The quadratic equation is \( x^2 + 8x + 6 = 0 \).
