given:
x+=+-5....................(1)
x+=+-3....................(2)
Add 5 to both sides of (1)
Add 3 to both sides of (2)
x+%2B+5+=+0..................(1)
x+%2B+3+=+0...................(2)

Their product also = 0
%28x+%2B+5%29%28x+%2B+3%29+=+0
x%5E2+%2B+3x+%2B+5x+%2B+15+=+0
x%5E2+%2B+8x++%2B+15+=+0.... answer
