Subtract*
(8b^4 – b^3) – (b^4 + 4b^3 – 4)

The equation is b³(7b-5) + 4

Explanation:

Given:

(8b⁴ - b³) - (b⁴ + 4b³ - 4)

We need to simplify the equation

During subtraction while opening the brackets, the sign of the variables gets reversed.

- becomes + and + becomes -

Thus, the simplified equation is b³(7b-5) + 4

answer: the answer is simply nothing.
