1.Use three or solon sentences to exposit how you would cipher the following leveling using factoring. 2×2-13x-7=0
2.Use three or solon sentences to exposit how you would cipher the following leveling by graphing. 2×2-13x-7=0
3.Use three or solon sentences to exposit how you would cipher the following leveling using the quadratic formula. 2×2-13x-7=0
4. Which of the following methods do you prefer? Why?
5.Graph the quadratic leveling (y = 2x 2-13x-7) using the MathResources graphing tool; and confiscate it with this assignment in the Assignment Area. Note: You may need to change the values of x-from & to and y-from & to so that the whole parabola will be circumpolar on the grid. Also spend as taught in state 5 under graphing. Otherwise I will have to send it back. To use the graphing tool click on the fix below.
6.What are the values of the roots you found using track points? ammo to the close hundredths.
I just dont understand so please dont indite a smart saying

we open two bracket to solve this equation :
( )( )=0
asking your self what are the two number that the multiple of them = 7 and the sum is = -13
( 2x + 1 )( x – 7 )=0 the two numbers are :
x=7 or x=-12
