obligation abet want to find the X , Xsquare+8x=9.?

x^2 + 8x - 9=0



(x +9)(x-1)=0



which give



X = 1 or -9
X=1 Try X=any positive # > 1, and your answer will be greater than 9. Try -2, and your answer is -12. Try -3, and your answer is -15. So you're getting further away from 9 with cynical #s.



If you plug in -1, your answer is -7. So it have to be a small positive #, and 1 is the only solution.



-8 does NOT work because your final answer will be ZERO not 9.
