A: What are the solutions to the quadratic equation x2+9=0? B: What is the factored form of the quadratic expression x2+9? Select one answer for question A, and select one answer for question B. B: (x+3)(x−3) B: (x+3i)(x−3i) B: (x−3i)(x−3i) B: (x+3)(x+3) A: x=3 or x=−3 A: x=3i or x=−3i A: x=3 A: x=−3i

A. The solutions are .

B. The factored form of the quadratic expression

Step-by-step explanation:

A. To find the solutions to the quadratic equation you must:

The solutions are:

B. Two expressions are equivalent to each other if they represent the same value no matter which values we choose for the variables.

To factor :

First, multiply the constant in the polynomial by where is equal to -1.

Since both terms are perfect squares, factor using the difference of squares formula

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

40,000*2=80,000 day 6
