Question

.
The value of a if (x - a) is a factor of x⁶-ax⁵+x⁴- ax³+3x - a + 2 = 0, is

​

Answer 1

Answer:

a = -1

Step-by-step explanation:

If X - a is a factor of the equation then we can say that x = a

now, putting the value of a in the equation we get,

a^6 - a.a^6 + x^4 - a.a^3 + 3x - a+2 =0

or, 3a - a + 2 = 0

or 2a + 2 = 0

or, 2(a + 1) = 0

or, a + 1 = 0

therefore a = -1

The value of a is -1.
