We are asked to transform the equation <span>3x^2+3x+2y=0 into the standard form by applying the technique of completing the square .
</span><span>3(x^2+x +1/4) =-2y + 3/4
</span>3 (x +1/2)^2 = -2 (y -3/8)
-3/2 (x +1/2)^2 = (y -3/8)
this follows the standard from <span>y-b=A(x-a)^2</span>

Answer:
Infinite triangles
Step-by-step explanation:
A triangle can have angles which total to 180 degrees
When one triangle ABC is constructed with degrees 80, 80 and 40 respectively, then similar triangles can be formed by transforming ABC with a real scale factor say k
k can take any real values positive, negative, rational, irrational etc.
Hence we can say given a triangle ABC with given angles there can be an infinite number of triangles with the same angles which will be similarl to ABC and carry an equal proportion with corrresponding sides.
