"( )" are parentheses ... "(" open parenthesis, and ")" close parenthesis "[ ]" are brackets ... "[" open bracket, and "]" close bracket Also to avoid confusion when using quadratic formula: use x and y NOT a and b. So use x^2 - y =13 and y^2 - x = 13

Presenter, please note that the way KZbin recommends items means that some of us just recently saw your video on the corresponding case for a & b being 8 & -9. This time you just added the a=b cases, but most of the presentation was naturally just repetition.

Две параболы пересекаются в четырёх точках. Две из них легко находятся подбором, у остальных a=b - обычное квадратное уравнение через дискриминант. Задача на две минуты максимум.

can't use b to be two different variables at 3:46

a = - 4 and b = 3 are satisfying values
@alfredhorstman3 күн бұрын
Easy. a = -4, b = 3.
@KrytenKoro2 күн бұрын
Have to get the a=b case too
