Use the distributive rule of algebra. This is not geometry.
2X^3(4 - 3X) -5X(X - 2).
2X^3*4 + 2X^3(-3X) -SX*X -5X*(-2) =
8X^3 - 6X^4 -5X^2 + 10X =
Arrange exponents in decreasing order:
-6X^4 + 8X^3 -5X^2 + 10X.
2X^3*4 + 2X^3(-3X) -SX*X -5X*(-2) =
8X^3 - 6X^4 -5X^2 + 10X =
Arrange exponents in decreasing order:
-6X^4 + 8X^3 -5X^2 + 10X.
The question is not about trigonometry.
