Question

If the polynomial 6x4 + 8x3 - 5x2 + ax + b is exactly divisible by polynomial 2x2-5, then find the value of the
a and b
​

Answer 1

Answer:

Make 2x^2-5=0

x=+-root(5/2)

Put x=+root(5/2)in polynomial making zero,

f(+(root5/2))=0

Similarly,

f(-(root5/2))=0

Thus two equations in variable a and b. Solve these and find out
