-2(h+5)(h-7) Take out the GCF: -2(h^2-2h-35) You want to find the factors of -35 that add to get -2 Those numbers would be 5 and -7 since they multiply to get -35 and add to get you -2
The percent decrease is found by using the formula (original price - new price)/(original price). The percent decrease is then (2.49 - 1.99)/2.49 = 0.20 = 20%. A percent increase is found by using the formula (new price - original price)/(original price). The percent increase is then (2.49 - 1.99)/1.99 = 0.25 = 25%. The percents of change are not the same. The percent increase is greater.
