Question

answer please step by step​

Answer 1

given

p(x)=ax³-3x²+4

p(x)2x³-5x+a

step by step...

g(x) x-2=0

x=2

put the value x=2 in I equation

a(2)³-3(2)²+4=p

8a-12+4=p

p=8a-8

now put the value x=2 in equation 2

2(2)³-5(2)+a=q

16-10+a=q

q=a+6

now according to question

p-2q=4

now put the valu p and q

8a-8-2(a+6)=4

8a-8-2a-12=4

6a=4+8+12

hence the value of a =4

hence proved
