use the quadratic formula since there isn't a factor of 60 that when added together equals 19 The above answer is wrong because 4 and 15 are such numbers. x2 + 19x + 60 = x2 + 4x + 15x + 60 = x(x + 4) + 15(x + 4) = (x + 4)(x + 15)
4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27
3x2 + 27x +60
9x = 60x = 60/9 = 6 2/3 (or 6.67)
