Question

1+2x is a factor of x³-ax²-ax+1 . Find a

Answer 1

Heyyy,

Given,

x - a is a factor of

we know,

x - a = 0

x = 0+a = a

Substitung the value of x as a,

we have,

(a)^3 - a(a)^2 + 2(a) + a - 1 =0

a^3 - a^3 + 2a + a - 1=0

3a - 1=0

3a =1

a = 1/3

Thus

a = 1/3

Hope that helps♥️

Answer 2

Answer:

a = 2

Step-by-step explanation:

1 + 2× = 0

2x =-1

x = -1/2.

${x}^{3} - ax + 1$

putting the volume of x = -1/2.

$\frac{ - 1}{2} - a \times ( \frac{ - 1}{2} ) + 1$

a= 2
