for x = -2: x2 = 4, -5x2 = -20; 3x = -6 giving -20 - (-6) = - 20 + 6 = -14.

Given a value of x, find the value for -3x + 2
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
-5*2-3x+4 when x=-1 is -10-3*(-3)+4=-10*9+4=3
Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
