Question

If x=2 and x= 0 zeros of polynomial p(x)= 2x cube-5x+ax+b

Answer 1

Answer:

A= 1 , B=0

Step-by-step explanation:

x=2,0

p(2)=2*2*2-5*2 +2a+b=0

8-10+2a+b=0

-2+2a+b=0

2a+b=2 ----- equation 1

p(0)= 0 -5*0+0a+b=0

0+0a+b=0

0a+b=0--------- equation 2

Subtract equation 2 from equation 1

 2a+b=2

-(0a+b=0)

2a=2

a=1

Substitute the value of "a" in equation 1

2a+b=2

=2*1+b=2

=2+b=2

b=2-2

b=0
