(x + 1)(x + 8)

x(x + 8) + 1(x + 8)

x*x + 8*x + 1*x + 1*8

x² + 8x + x + 8

x² + 9x + 8

Hope this explains it.

Which rational number is one tick mark to the left of -3/4
Zolol [24]

I'm assuming each tickmark is 1/4 = 0.25

If that assumption is correct, then going one tickmark to the left of -3/4 lands you on -4/4 which simplifies to -1.

So -1 is one tickmark to the left of -3/4

Again, this all hinges on the assumption that each tickmark is 1/4 a unit away from its neighbor.
