Simplification of polynomials
To simplify a polynomial as much as possible, group all like terms and rearrange them from highest to lowest power.
Expand the distribution of terms.
4 ✖ 3 ➕ 4 ✖ ➖4x
Multiply 4 by 3.
12 ➕ 4 ✖ 4x
Multiply 4 by ➖4x.
12 ➖ 16x
herefore in exercise 4(3 - 4x) the answer or solution is 12-16x. so the correct option is alternative "C".
