Cho hàm số y = x^3 + (m+1)x^2 + (2m-1)x+6. Tìm m để hàm số a) đạt cực đại tại x=-2
b) đạt cực tiểu tại x =5
c) có hai cực trị

sorry not knowing about that

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.

y-y1=m(x-x1)

y-1=1(x-8)

no solution exists the way you wrote the equation.
