the finished factorization of right here polynomials are as follows: (a) 2a^2 - 4a - 2 = 2(a^2 - 2a - a million) observe that the polynomial expression a^2 - 2a - a million is already top, i.e., a^2 - 2a - a million isn't factorable, each time a is an integer. (b) t^2 - 9w^2 = (t - 3w)(t + 3w)

2x(x^2-2x-15)=2x(x-5)(x+3)
2(x^4-3x^2-4)=2(x^2-4)(x^2+1)
=2(x+2)(x-2)(x^2+1)
