209 Having a calculator helps.
6x3 - x2 + 17 = 2x2 + 47 6x3 - x2 - 2x2 = 47 - 17 x2(6x - 1 - 2) = 30 this is the simplest factorisation.
2x2 + 6 = 30 is your statement.2x2 = 24x2 = 12x = ±√12x = ±√(4*3)x = 2√3 or x = -2√3
20X2 + 3010(2X2 + 3)============That's as much factoring as can be done here.
MMDCXXX stands for 2000+600+30 = 2630
By using the quadratic equation formula: x = -5 and x = 3
Some plusses and/or minuses would have assisted. (2x - 5)(x + 6) are factors of 2x2 + 7x - 30, giving solutions for x of 2.5 and -6; (2x + 5)(x - 6) are factors of 2x2 - 7x - 30, giving solutions of -2.5 and 6.
30 + 30 + 30 + 30 + 30 + 30 = 180
