Question

p(x)= (x-1) (3x-1) then p(1/3) =.​

Answer 1

Answer: -1

Step-by-step explanation:

x²+3x-1.

p(x-1) is (x-1)²+3x-3-1

x²+1-2x+3x-4

x²+x-3.

given they are equal so,

x²+x-3=x²+3x-1

x-3=3x-1

x=-1

answer is -1

Answer 2

For, x = -1/3, p(x) = 3x+1

∴p(−1/3) = 3(-1/3)+1 = −1+1 = 0

∴ -1/3 is a zero of p(x).
