Question

What is the expression (x-3)(x^2-3x-10) as a polynomial in standard form?

Answer 1

A polynomial in standard form only means that you put it in order of descending x values. Multiplying out those 2 factors gives us $x^3-3x^2-10x-3x^2+9x+30$. Combining like terms and we have $x^3-6x^2-x+30$. That's in standard form.
