2x² + 5x -6x - 15 = 0
2x² - x - 15 = 0
2x² -x = 15
x = 3
3 x 3 = 9 x 2 = 18 - 3 = 15
i really don't know how i got 3 in the first place but that is your answer
hope this helps
Answer:
32
Step-by-step explanation:
Substitute p=-2 into the equation and solve.

7 1/10 is the answer bc you have the plain 7 and .1 is 1/10
28/5, you cross multiply so 4/5=y/7 would become 5y=28 then you solve for y from there which becomes 28/5
