Please, factor this polynomial: \(x^3 + 1\)

From the special product rule:

\(a^3 + b^3 = (a + b)(a^2 – ab + b^2)\)

We have: \(x^3 + 1 = (x + 1)(x^2 – x + 1)\)

Factor the polynomial. \(t^4 - 1\)

Factor the polynomial. \(r^4 – 81\)

Please, multiply: \(3(3m + 4n) (m + 2n)\)

Please, multiply these polynomials: \((3t – 7)(1 + 3t^2)\)
