The cube of polynomial x-4x + nx-2x-5 is equal to the cube of polynomial x + 3x + MX + 4x-5

The cube of polynomial x-4x + nx-2x-5 is equal to the cube of polynomial x + 3x + MX + 4x-5


Cube of X - 4x square + NX square - 2x-5 = cube of X + 3x square + MX + 4x-5
Cube of X + (n-4) square of x-2x-5 = cube of X + square of 3x + (M + 4) X-5
n-4=3,m+4=-2
n=7,m=-6



When x = - 2, the cube of MX + the square of 4x - 3mx + 32 is 10. What is the value of polynomial when x = 2


Let f (x) = MX & sup3; + 4x & sup2; - 3mx + 32; f (- 2) = - 8m + 16 + 6m + 32 = - 2m + 48 = 10; m = 19
f(2)=8m+16-6m+32=8*19+48-6*19=38+48=86



If the square of polynomial 2mx + (- 2m + 4) x-3x-1


The square of 2mx + (- 2m + 4) x-3x-1
=The square of 4x-3x-1
