Complete the square 4y^2+3x^2=3-x

First, let's rewrite the equation in standard form:

4y^2 + 3x^2 + x - 3 = 0

To complete the square for the y terms, factor out the 4 in front of y^2:

4(y^2 + (3/4)y) + 3x^2 + x - 3 = 0

Next, complete the square for the y terms by adding and subtracting (3/8)^2 = 9/64:

4(y^2 + (3/4)y + 9/64 - 9/64) + 3x^2 + x - 3 = 0

Now, rewrite the y terms as a perfect square trinomial:

4(y + 3/8)^2 - 9/4 + 3x^2 + x - 3 = 0

Rearranging the terms:

4(y + 3/8)^2 + 3x^2 + x - 3- 9/4= 0

Multiplying throughout by 4:

16(y + 3/8)^2 + 12x^2 + 4x - 12 - 9 = 0

Now the equation is in the form of a completed square.
