The polynomial 6x 3 + x 2 + ax 10, where a is a constant, is
Question:
The polynomial 6x3 + x2 + ax − 10, where a is a constant, is denoted by P(x). It is given that when P(x) is divided by (x + 2) the remainder is −12.
a. Find the value of a and hence verify that (2x + 1) is a factor of P(x).
b. When a has this value, solve the equation P(x) = 0.
