= x(1-4x^2)From difference of two squares method,= x(1-2x)(1+2x)

The vector equation of any line is composed of the addition of a point on the line and some distance in the direction of the line, in the form y=(x,y,z) +d(x_1, y_1, z_1), where (x,y,z) is any point on th...

First, you would need to differentiate the equation. To find the differential, multiply the power of x by the coefficient, then reduce the power by 1. You should see that any constants will not be seen in...
