Sure, fill in x as the numbers on the table, and the correct answer is A
1.) 1.67×10 to the power of 9
2.) 1.133×10 to the power of -3
3.) 1.75×10 to the power of 9
4.) 2.64×10 to the power of 4
5.) 2.947×10 to the power of -6
6.) 4.24×10 to the power of 5
7.) 1.0207×10 to the power of 6
8.) 1.027×10 to the power of 5
X^2 - 8x-9=0
D = b^2- 4*a*c = 64- 4* (-9) = 64+36=100 =10^2
X1 = (8-10)/2 = -1
X2= (8+10)/2= 9
