Given:

The expression is

[tex]x+4x-3+3x^2-2x[/tex]

To find:

The value of given expression when x=5.

Solution:

We have,

[tex]x+4x-3+3x^2-2x[/tex]

Substituting x=5 in the above expression, we get

[tex]=(5)+4(5)-3+3(5)^2-2(5)[/tex]

[tex]=5+20-3+3(25)-10[/tex]

[tex]=5+20-3+75-10[/tex]

On further simplification, we get

[tex]=(5+20+75)+(-3-10)[/tex]

[tex]=100+(-13)[/tex]

[tex]=100-13[/tex]

[tex]=87[/tex]

Therefore, values of the given expression at x=5 is 87.
