Given : 2 & 0 are the zeroes of the polynomial f(x)=2x-5 x2 +ax +b
To Find : the value of a and b
Solution:
polynomial f(x)=2x-5x² +ax +b
2 & 0 are the zeroes of the polynomial f(x
=> f(2) = f(0) = 0
f(0) = 0
=> 0 - 0 + 0 + b = 0
=> b = 0
f(x)=2x-5 x² +ax +b
b = 0
=> f(x)=2x-5 x² +ax
f(2) = 0
=> 2(2) - 5(2)² + a(2) = 0
=> 4 - 20 + 2a = 0
=> 2a = 16
=> a = 8
Hence a = 8 , b = 2
if f(x) = x² + ax + b
Then 0 + 0 + b = 0
=> b = 0
2² + 2a + 0 = 0
=> a = - 2
Then a = - 2 and b = 0
