I don't know how to do this. Can someone help me.

Break up the x-2 and use distributive property to multiply.

X(x3 +7x2 +2x -40) -2 (x3 +7x2 +2x -40)

Idon’t feel like doing the math but you need to do 2.24 divided by 7

I’m pretty sure the * means multiplication. so, if you multiply 5*1, it would equal 5. they are basically are-writing 5x1 as 5*1. so they would be… 5 10152025303540455055
