Question

PLEASE HELP! I AM REALLY CONFUSED! find the value of a if X^3+8x^2+ax-2 is divisible by x-1

Answer 1

The value of a from the equation is -63.

Here we have to find the value of a.

Given data:

The equation is = x³ + 8x² + ax -2

The equation is divisible by x -1

So we have:

x -1 = 0

x = 1

Now putting the value in the equation we get the remainder as o because the equation is divisible by x -1.

So;

1³ + 8² + a(1) - 2 = 0

63 + a = 0

a = -63

Therefore we get the value of a as -63.
