Question 1208745
<br>
(x + 2)(3x^2 + 12) + (x - 2)<br>
In the first part of the expression, multiply each term of the first polynomial by each term of the second.<br>
x(3x^2) = 3x^3
x(12) = 12x
2(3x^2) = 6x^2
2(12) = 24<br>
The product of the two polynomials is the sum of those partial products<br>
3x^3+6x^2+12x+24<br>
When adding the last part of the expression, combine like terms if there are any.<br>
(3x^3+6x^2+12x+24) + (x-2) = 3x^3+6x^2+(12+1)x+(24-2)<br>
ANSWER: 3x^3+6x^2+13x+22<br>
