2. ### If the height of an equilateral triangle is also a root pf the equation y^4-3y^2-270, then the area of the triangle is?

y^4 - 3y^2 - 270 = 0 y^2 = (3 +/- sqrt(9 + 1080)) / 2 y^2 = (3 +/- sqrt(1089)) / 2 y^2 = (3 +/- 33) / 2 y^2 > 0 y^2 = (3 + 33) / 2 y^2 = 36/2 y^2 = 18 y = +/- 3 * sqrt(2) y = 3 * sqrt(2) So, the height is equal to 3 * sqrt(2) (s/2)^2 + h^2 = s^2 (s/2)^2 + 18 = s^2 s^2 / 4 + 18 = s^2 18 = (3/4) * s^2 18 * (4/3) = s^2 24 = s^2 2 * sqrt(6) = s A...
