The answer is 0.08 or you could say 8 * 10^-2.

Reasoning..
6.4 * 10^3 = 6400
8 * 10^4 = 80000

Divide those two numbers like shown in the problem and boom!

Answer:

Kim

Use factoring to solve the quadratic equation x2 − 2x − 3 = 12.
melomori [17]

Answer:

x_1=5\\x_2=-3

Step-by-step explanation:

You have the following quadratic equation given in the problem:

x^{2}-2x-3=12

You must make the equation equal to zero, as following:

x^{2}-2x-3-12=0

Add like terms:

 x^{2}-2x-15=0

Now, to factor the equation, you must find two numbers whose sum is -2 and whose product is -15. Therefore, you have:

(x-5)(x+3)=0\\x_1=5\\x_2=-3
