Area=legnth times width
so multiply them together use distributive property
a(b+c)=ab+ac so
in this problem
(a+b)(c+d+e)=(a+b)(c)+(a+b)(d)+(a+b)(e)
so
x^2-2 times (2x^2-x+2)=(x^2)(2x^2-x+2)-(2)(2x^2-x+2)=(2x^4-x^3+2x^2)-(4x^2-2x+4)
add like terms
2x^4-x^3+(2x^2-4x^2)-2x+4
2x^4-x^3-2x^2-2x+4

find the smallest and largest squares
oh, nevermind an easier way
square root them
4 million=4,000,000
square root=2000
9million=9,000,000
square root=3000
how many numbers betwee 2000 and 3000?
3000-2000=1000
minus 1 because of math
999 numbers fit the criteria
