Question 1209342
<br>
{{{(x^3 + x^2 + x + 1)(5x^7 - 3x^4 + 10x^2 - 15)}}}<br>
The partial products that contribute to the x^2 term in the product come from multiplying....<br>
(1) the x^2 term in the first polynomial and the constant term in the second: (x^2)(-15) = -15x^2
(2) the x term in the first polynomial and the x term in the second: (x)(0x) = 0x^2
(1) the constant term in the first polynomial and the x^2 term in the second: (1)(10x^2) = 10x^2<br>
(-15x^2) + (0x^2) + (10x^2) = -5x^2<br>
ANSWER: the coefficient of x^2 in the product is -5<br>
