Answer is 357 cm squared
Multiply each term in one bracket by each in the other:
<span>(I assume x2 means x^2 / x squared) </span>
<span>(x^2 + 3x + 1)(x^2 + x + 2) </span>
<span>= x^4 + x^3 + 2x^2 + 3x^3 + 3x^2 + 6x + x^2 + x +2 </span>
<span>Now collect all terms: </span>
<span>= x^4 + 4x^3 + 6x^2 + 7x + 2 </span>
