This is an expression and you do not solve an expression, but you can factor this one.X2 + 3X4X2(1 + 3X2)========
3x4x last side. there are not only 2 dimensions. 3x4x1=12 3x4x2=24 3x4x3=36 3x4x4=48
(x4 - 2x3 + 2x2 + x + 4) / (x2 + x + 1)You can work this out using long division:x2 - 3x + 4___________________________x2 + x + 1 ) x4 - 2x3 + 2x2 + x + 4x4 + x3 + x2-3x3 + x2 + x-3x3 - 3x2 - 3x4x2 + 4x + 44x2 + 4x + 40R∴ x4 - 2x3 + 2x2 + x + 4 = (x2 + x + 1)(x2 - 3x + 4)
24
3*4*2 = 12*2 = 24
