Answer 2

To find the value of the expression $(x - 10)^2 - x + 80$ when $x = 0.98$, substitute $x$ with $0.98$ in the expression and perform the calculations:

$$(0.98 - 10)^2 - 0.98 + 80$$

First, calculate $0.98 - 10$:

$$= (-9.02)^2 - 0.98 + 80$$

Now, calculate $(-9.02)^2$:

$$= 81.3604 - 0.98 + 80$$

Next, add $81.3604$ and $80$:

$$= 161.3604 - 0.98$$

Finally, subtract $0.98$ from $161.3604$:

$$= 160.3804$$

So, when $x = 0.98$, the value of the expression $(x - 10)^2 - x + 80$ is approximately $160.3804$.
