Question

If P(x)= 6x^3+ 7x - 3. The value of P(-1) + P(1) is
pls ans if u don't know no need to tell sorry just skip this question​

Answer 1

Answer:

Given that,

α,β  are the zeroes of the polynomial  p(x)=2x2−7x+3

Sum of zeroes (α+β)=a−b=2−(−7)=27

Product of zeroes αβ=ac=23

∴α2+β2=(α+β)2−2αβ

                    =(27)2−2(23)

                    =449−412

                    =437
