The polynomial equation [tex]2x^{3} - 5 x^{2} + x + 2 = 0[/tex] given that 2 is zero of
f(x) = [tex]2x^{3} - 5 x^{2} + x +2[/tex]
According to the question,
f(x) [tex]=2x^{3} - 5 x^{2} + x + 2[/tex]
[tex]f(2)= 2(2)^{3} - 5 (2)^{2} + 2 + 2 \\= 2(8) - 5(4) +4\\= 16 - 20 + 4\\= -4 + 4\\= 0.[/tex]
Hence, the polynomial equation [tex]2x^{3} - 5 x^{2} + x + 2 = 0[/tex] given that 2 is zero of f(x) [tex]=2x^{3} - 5 x^{2} + x + 2[/tex].
