Use the method of completing the square to transform the quadratic equation into the equation form (x + p)^2 =q using the equation 6 + 12x + 3x^2 = 0

Step-by-step explanation:

6+12x+3x²=0

3x²+12x=-6

x²+4x=-2

x²+4x+4=-2+4

(x+2)²=2

p=2

q=2

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
