Question

The value of the expression x^4-8x^3+18x^2-8x+2 when x=2+3

Answer 1

Step-by-step explanation:

x=2+3=5

therefore the expression will be,

5^4-8(5^2)+18(5^2)-8(5)+2

625-8(25)+18(25)-45+2

625-200+450-43

625-250-43

Answer 2

$\sf\color{navy}{Given:-}$x=2+3 i.e 5

$\sf\color{navy}{To\:Find:-}$ Value of expression x⁴-8x³+18x²-8x+2

$\sf\color{navy}{Proof:-}$

5⁴-8(5²)+18(5²)-8(5)+2

625-8(25)+18(25)-45+2

625-200+450-43

625-250-43
