Question

if (a+3) is a factor of p(a)=a^3+xa^2+a+3 then x=______​

Answer 1

Step-by-step explanation:

$ques..$

$p(a) = {a}^{3} + xa {}^{2} + a + 3$

$p( - 3) = ( - 3) {}^{3} + x \times ( - 3) {}^{2} + ( - 3) + 3$

$- 27 + x \times 9 - 3 + 3$

note; -3 +3 (cancel )...

$- 27 + 9x$

$x = \frac{ - 27}{9}$

$x = - 3$

$answer$
