The heat of fusion is the amount of energy required to change one mole of a substance from solid to liquid at its melting point without changing its temperature. This term accurately reflects the phase change described.
I. 64x2 - 64x + 15 = 0
II. 21y2 - 13y + 2 =0
I.70x² - 143x + 72 = 0
II. 80 y² - 142y + 63 = 0
If x2 - 3x - 18 = 0 and y2 + 9y + 18 = 0, which of the following is true?
I. 12x2- 55x + 63 = 0
II. 10y2- 47y + 55 = 0
(i) 2x² + 14x - 16 = 0
(ii) y² – y – 12 = 0
The roots of the equations x2 + 16x + 63 = 0
