Answer:
29. (5,0) and (-7/2,0)
30. (-1,0) and (5/7,0)
Step-by-step explanation:
29. y=2x² - 3x - 35
y = (x-5)(2x+7)
y is 0 at x = 5 and -(7/2)
31: y=-7x² - 2x + 5
y = -(x+1)(7x-5)
y is 0 at -1 and 5/7
See the attached graph.
You left out the 9 in the whole equation. The 1st step you had right you just forgot to put +9. 2nd step you are combining the like terms and get 11-26x=-34x+40. Step 3: you are trying to isolate the x on one of the sides. You need to switch the 11 over to the 40 and get 29. Move -34x over to -26x and get 8x. Step 4 all you are doing in dividing 8 from both sides and get 5.
