Answer:
The difference of two squares occurs when the middle term or "b" of your polynomial is absent. so the the "c" term would have to be the product of a single number, one positive and one negative. if c = 3 then x2 - 9 = 0 factors to (x+3)(x-3) = 0 and so on.
Step-by-step explanation:
Hi there! :) The answer to your question is 3. First you do parenthesis r=3.
3+7=10, then you do 10*2=20. That is how you solve the problem.
Hope I helped! :)

The two numbers that would multiply to equal the value on top and add to the value on the bottom would be -2 and 9.
-2 x 9 = 18
-2 + 9 = 7
Quotient is the result of dividing two numbers.
x= the unknown number
The equation is x divided by 9 equals x minus 40.
x/9= x - 40
multiply both sides by 9
(9)(x/9)= (9)(x - 40)
x= 9x - 360
subtract 9x from both sides
-8x= -360
divide both sides by -8
x= 45
ANSWER: The number is 45.
Hops this helps! :)
