10^7 = 10,000,000
8.83*10000000 = 88300000

Question 2. How do I evaluate the polynomial for x= -2? The equation is 2x^2-5x+1. When x= -2, 2x^2-5x+1 equals ?
2x^2-5x+1
sub -2 for x
= 2*(-2)^2 -5(-2) + 1
= 8 + 10 + 1
= 19

Is it 10^7 or 10^(-7)?
Your explanation is a bit confusing.
If it's positive 7 then it's like multiplying by 10000000, 88300000.
If it's negative 7 then it's like multiplying by 10000000, 0.000000883.

Substitute (-2) wherever you see an x.
Work that through and you'll have your answer.
