Question

5. Find the zeroes of the polynomial f(x) = x3 - 4x2 + 5x – 2 if it is given that the product of its
two zeroes is 1.
0. Find the values of m and n so that x4 + x3 + 8x2 + mx + n is exactly divisible by x? +1.​

Answer 1

Step-by-step explanation:

so First one is a cubic polynomials

Let zeroes be x , y and z

given xy = 1

We know xyz = -d/a

i.e z =-d/a

Z = 2/1

so the third zero is 2

now we know xy + yz +za = c/a
