After manipulating above equation we get, 2x^2 - 7x - 8= 0. Discriminant= b^2 - 4ac = (-7)^2 - 4(2)(-8) = 113>0. So there are 2 real roots :)
Answer:
Your expression would be 9x + 3y

Please mark brainliest if this helped! :)
{(3,0),(6,1),(9,2)} because
when you plug in the values you get
3-3=3(0) = 0=0
6-3=3(1) = 3=3
9-3=3(2) = 6=6
