Question

What is the value of 1/2 x2 -10 when x = 6?

Answer 1

The numerical value of expressions

We are given the expression:

`P=(1)/(2)x^2-10`

It's required to find the value of the expression when x=6

Substituting:

`P=(1)/(2)6^2-10`

Since 6 squared is 36:

`P=(1)/(2)36-10=18-10=8`

The value is 8
