To find the solutions, set the equation equal to 0. You get
. We are going to factor our things that both terms have in common, a 2, and an x. This gives you
. How do you know this is true? If you distribute back out, you get the same as the original problem.
Now set these both equal to zero. 2x = 0, 2x + 17 = 0. Divide both sides by 2, you get one solultion of x = 0. For the other solution, subtract 17 from both sides; 2x = - 17. Divide by 2, x = -17/2
Your solutions are x = {- 17/2, 0}
To check, plug these back into the original equation to see if they equal zero. 4(0)^2 + 34(0) = 0 + 0 = 0
4(- 17/2)^2 + 34(- 17/2) = 289 + (- 289) = 289 - 289 = 0

Answer: D) 4</h3>
Explanation:
Start at the point (-1,-4). In order to move to (0,0), we must do the following two steps:
- Move 4 units up
- Move 1 unit to the right
This indicates slope = rise/run = 4/1 = 4.
You could use the slope formula to get this same result.
Slope = 1/2 y-intercept = 5/3 so y=1/2x+5/3
