The solutions to a quadratic question are -6 ans +6. you figure it the original equation and write it in standard form ax2+bx+c=0. what is the value of "b"?

this must be (x+6)(x-6)

when that is multiplied out you get

so there would be no b, b therefore is equal to zero in this equation

Step-by-step explanation:

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5
