Answer:

f x =2x³-5x²+ax+b

f2=2(2)³-5(2)²++$+$

Verified answer

Answer:

a = -2

b = 0

Step-by-step explanation:

x= 0 and x= 2 are the roots of this equation so if we put these values the equation will produce 0

so firstly we put x = 0

the equation will be 0 - 0+ a.0 + b = 0

basically b = 0

now if we put the second root x = 2

then the eq. 16 - 20 + 2a + 0 = 0

so we get a = -2

thus a = -2

b = 0
