Find two numbers whose difference is 140 and whose product is a minimum

If x is the smaller number, then the product is x(x+140). This expression describes an upward-opening parabola with zeros at 0 and -140, hence a minimum at x = -70.

Your two numbers are -70 and 70. Their product is -4900.

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial
