Haley substituted the values of a, b , and into the quadratic formula below. X = (- (- 10) plus/minus sqrt((- 10) ^ 2 - 4(7) * (- 2)))/(2(7)) What was Haley's function in standard form? I f(x)= Box x^ 2 + Box x^ 2 + Box

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
