The main reason behind this is using properties of logarithm .

when solving
There you use multiplication property and make addition to multiplication then you get extraneous solution because in plenty of cases they occur

But
Same happens in case of logarithm
Answer C is correct. If angle 1 + angle 2 = 180 degrees then L is parallel to M.
Co interior angles are only supplementary in parallel lines
Combine like terms to get -4x^2-2x
Answer: The answer that is not true is choice D.
If Katie drew those chords and those line segments to form a square, then the diagonals would have to be congruent. The only way to have them would be through the center, therefore they must be diameters.
And if it is a square, then the diagonals are perpendicular bisectors meaning the angles would be right angles not acute or obtuse as in Choice D. <span />
