3x2 - 16x + 5 = 3x2 - x - 15x + 5 = x(3x - 1) - 5(3x -1) = (3x - 1)(x - 5) or I would use the quadratic equation. 3X^2 - 16X + 5 = 0 X = -b +/- sqrt(b^2-4ac)/2a a = 3 b = -16 c = 5 X = -(-16) +/- sqrt[(-16)^2 - 4(3)(5)]/2(3) X = 16 +/- sqrt(256 - 60)/6 X = 16 +/-sqrt(196)/6 X = (16 +/- 14)/6 X = 5 X = 1/3 check the easy one 3(5)^2 - 16(5) + 5 = 0 75 - 80 + 5 = 0 0 = 0 easy one checks; you try the 1/3 check
