Step-by-step explanation:
[tex]\longrightarrow\sf{ p(x) = 2{x}^{4} - 5{x}^{3} + 7x - 3}[/tex]
- Now, substituting the value of x in equation, we get.
[tex]\longrightarrow\sf{ p(2) = 2({2})^{4} - 5{2}^{3} + 7\times 2 - 3}[/tex]
[tex]\longrightarrow\sf{ 2\times 16 - 5\times 8 + 14 - 3}[/tex]
[tex]\longrightarrow\sf{ 32 - 40 + 14 - 3}[/tex]
[tex]\longrightarrow\sf{ - 8 + 14 - 3}[/tex]
[tex]\longrightarrow\sf{ + 6 - 3}[/tex]
[tex]\longrightarrow\sf{ 3 }[/tex]
