Question

Simplify the expression to a polynomial in standard form: (3x + 10) (2x² - 2x + 3)

Answer 1

Step 1

Write out the question.

`\begin{gathered} (3x+10)(2x^2\text{ - 2x + 3)} \\ =3x(2x^2-2x+3)+10(2x^2\text{ - 2x + 3)} \\ =6x^3-6x^2+9x+20x^2\text{ - 20x + 30} \\ =6x^3+14x^2^{}-11x+30^{} \end{gathered}`
