Hello :
This number is : x
you have : x + 2x² = 6
2x² + x -6 = 0
Δ = b² -4ac a = 2 , b = 1 , c = 6
Δ = 1² - 4(2)(6) = 49 = 7²
X1 = (- 1 +7)/4 = 3/2
X2 = (-1-7)/4 = -2
Answer:
The linear approximation is ;
F(x,y) = x -5y - 1
Step-by-step explanation:
Here, we want to find the linear approximation of the given function at the indicated point.
We start by substituting the values then after wards finding the partial derivative with respect to x and then to y.
We finish by adding up these values after substituting the values of x and y into the differentiated partial equation. We then add up our results.

Consider the following Argand-diagram
enter image description here
The y-axis is the imaginary axis and the x-axis is the real one. The complex number in question is
x+yi
To figure out θ, consider the right-triangle formed by the two-coordinates on the plane (illustrated in red). Let θ be the angle formed with the real axis.
tanθ=yx
⟹tan−1(yx)
The hypotenuse of the triangle will be
x2+y2−−−−−−√
Therefore,
