6.2 Solving Quadratic Equations by Factoring

        Billy Bob is a Rocket Scientist with NASA. He is trying to find out  how far his rocket will fire into the air. To find this out he must use this equation- x²+12x+36 he must get a altitude of at least one hundred and thirty feet. X stands for the fuel burned.

THE QUESTIONS

1. Solve for x by factoring the equation( show work)

2. What is the total amount of  fuel he will need

3. Is the outcome higher than 133 feet.        

THE ANSWERS

1. x=6 ( you should factor the problem like this: x²+12x+36; (x+6)(x+6); if you got a 5 and a 4 you would need to state both as the answer but since you got the same number you only state that one (6).

2.108 gallons (6²+12*6=108)

3. Yes the outcome is 144 feet.

Perseverance

"No matter how many times you fall down, you have to continue to get up. Quitting should not be an option."

(What this quote means is that if you do not give up you will not fail in what you want to do.)

All of my information I got from Glencoe Algebra II  text book on pages 341-345.
