Answer:
a = -2, b = 0
Step-by-step explanation:
Given, 2,0 are zeroes of the polynomial p(x)
p(x) = 2x³-5x²+ax+b
2x³-5x²+ax+b = 0
Substitute 2 in place of x to find a
2(2)³-5(2)²+a(2)+b = 0
16 - 12 + 2a + b = 0
4 + 2a + b = 0
2a + b= -4 (divide by 2 on both sides)
a + b = -2
a = -2 - b ... (i)
Substitute 0 in place of x to find b
2(0)³-5(0)²+a(0)+b = 0
0 - 0 + 0 + b = 0
b = 0 ... (ii)
Substitute (ii) in (i)
a = -2 - 0
a = -2
∴ a = -2, b = 0
