Question

4x^3 -16x^2-ax+17 (x-1)is of given equation find the value of . And factoraise the solution

Answer 1

Answer:

Step-by-step explanation:

Given: x-1=0(or x=1) is a factor of the equation

Put x=1 in equation

4(1)^3-16(1)^2-a(1)+17=0

or 4-16-a+17=0

or 5-a=0

or a=5

Now ; Putting the value of a

4x^3-16x^2-5x+17=0

or (x-1)(4x^2-12x-17)  [Dividing equation by x-1]
