Jane times everything by 100
karen timed 1.25 by 100
scott added x and 1.25x together
I suspect this is what you mean, if let me know
2x(3)^2+x(2)^2
2(3)(9)+3(4)
54+12=66
1-.63=.37. so $0.63+$0.37=$1.00
There are two negative roots to the provided polynomial function
f(x) = x⁷ – 2x⁴ + 7x² + 2x – 2
<h3>What is polynomial?</h3>
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

We have a polynomial function:
f(x) = x⁷ – 2x⁴ + 7x² + 2x – 2

Using the zero product property:

After solving:
x = -1, x = -0.853, and x = 0.418 (using the graph method)
Thus, there are two negative roots to the provided polynomial function
f(x) = x⁷ – 2x⁴ + 7x² + 2x – 2
