<span> A. x²+2 - a polynomial
B.(x⁸-2)/(x⁻²+3) rational function
C. 7x⁷-2x⁻⁴+3 (It has negative value of exponent, so it cannot be a polynomial.)
D.x^x-1 (x is an exponent it cannot be a polynomial)</span>
GCF= 1
FACTORED VERSION = (X-1) (2X+3)(X+2)
Remember that when you find 30% of the number you have to subtract the 30% from your original $90 because it is 30% off the original price.
