Which shows the correct substitution of the values a, b, and c from the equation -2=-x+x2- 4 into the quadratic formula? Quadratic formula: -bij 62 - 405 0x==(-1)Ã¥(-1)? - 4(1)(-4) 201)
Ox=-11/12-4-1X-4) 21-1) -11: (1)2 - 4 - 1X-2) 21-1)
Ox= -(-1) (-1- 4(1)(-2) 201) 18​

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
