Question

If 2 and 0 are the zeroes of the polynomial f(x)= 2x^3-5x^2+ax+b then find the values of a and b

Answer 1

here 2 and 0 are zero of polynomial(at 1st we take x=2)
=2(8)-5(4)+2a+b
=16-20+2a+b
now
2a+b=4
b=4-2a


now when x=0
0-0+2+0+b
b=-2

now

4-2a=-2
a=3
b=4-2a
b=4-6
b=-2

Answer 2

Answer:

The value of a=2

And the value of b=0
