Answer:
6x²–7x–3
middle term spilting
6x² – 9x + 2x -3
– 9x + 2x -33x(2x-3) +1 (2x-3)
(3x +1) (2x -3) = 0
3x +1 = 0
3x +1 = 0 ⇒ 2x -3 = 0
3x +1 = 0 ⇒ 2x -3 = 0⇒ x =3/2
3x +1 = 0 ⇒ 2x -3 = 0⇒ x =3/2⇒ x = – 1/3
sum of zeroes = -1/3 + 3/2 =7/6 = -b/a
sum of zeroes = -1/3 + 3/2 =7/6 = -b/aproduct of zeroes =- 1/3 * 3/2 = – 3/6 or -1/2 = c/a
