Math Problem Statement

Gambarkan grafik persamaan x^2 - 4x + 3y^2 = -2.

Solution

The image contains the equation:

x24x+3y2=2x^2 - 4x + 3y^2 = -2

The task is to "Gambarkan grafik persamaan" which means "Draw the graph of the equation" in Indonesian.

Let's analyze and simplify this equation step by step.

Step 1: Rearrange the equation

We start with: x24x+3y2=2x^2 - 4x + 3y^2 = -2 We want to transform this into a more recognizable form, such as for a conic section (ellipse, hyperbola, etc.).

Step 2: Complete the square for the xx-terms

The xx-terms are x24xx^2 - 4x. To complete the square: x24x=(x2)24x^2 - 4x = (x - 2)^2 - 4

Substitute this into the original equation: (x2)24+3y2=2(x - 2)^2 - 4 + 3y^2 = -2 Now, move the constant 4-4 to the right-hand side: (x2)2+3y2=2(x - 2)^2 + 3y^2 = 2

Step 3: Recognize the form

This is now an equation of an ellipse: (x2)22+y223=1\frac{(x - 2)^2}{2} + \frac{y^2}{\frac{2}{3}} = 1

This represents an ellipse centered at (2,0)(2, 0), with semi-major axis along the xx-axis and semi-minor axis along the yy-axis.

Conclusion

The equation describes an ellipse centered at (2,0)(2, 0), with axes lengths scaled by 2\sqrt{2} along the xx-axis and 23\frac{\sqrt{2}}{\sqrt{3}} along the yy-axis. You can now draw the graph based on these parameters.
