Answer 2

The answer is  x⁵-x⁴-x³-6x²+6x.

• While approximation involves lowering the mathematical statement to its closest value but is not quite correct, simplification refers to reducing the expression in a simpler form utilising a variety of processes.
• A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Expanding the given expression, we get:

(x²+2x+3)(x²-3)(x-1)

= (x²+2x+3)(x²)(x-1) - (x²+2x+3)(3)(x-1) {using (a+b)(c+d) = ac + ad + bc + bd}

= (x⁴+2x³+3x²)(x-1) - 3(x²+2x+3)(x-1)

= x⁵-x⁴+2x⁴-2x³+3x³-3x²-3x²+6x-3x⁴+6x³-9x²

= x⁵-x⁴-x³+3x²+6x-9x²

= x⁵-x⁴-x³-6x²+6x
