(2x4) + (8x3) + 18x 8 + 24 + 18x 32 + 18x
10x3 + 3x2
i thinking this answer should be -20
Windows calculator states it as... 2.9240177382128660655067873601379
3x1=7 1+7=8 8x3=24
(2x4) + (8x3) + 18x 8 + 24 + 18x 32 + 18x
10x3 + 3x2
is a quintic expression in x (NOT an equation).

8x3=24
3x1=7 1+7=8 8x3=24
It is a quartic equation in the variable x.
40-8x3 is equal to 16.
This is how I did it:8x3+4x2+6x+3[8x3+4x2]+[6x+3][(4x2)(2x+1)]+[(3)(2x+1)]....as you can see, this is in the general form of ab+cb, which factored is b(a+c), so:(2x+1)(4x2+3)
9x4 is 36 and 8x3 is 24
