Question 428727: find two consecutive odd whole numbers whose product is 63
can you show your work? because i want to know how to do it
THANK YOU^^ Answer by John10(297) (Show Source):
You can put this solution on YOUR website! Let x be the first ODD number then the next odd number is x + 2
The product is 63
x(x +2) = 63
x^2 + 2x - 63 = 0
(x + 9)(x - 7) =0
x = -9 OR x = 7
Since the question just needs the WHOLE number, so -9 is not the solution.
Thus the first number is 7 and the next one is 7 + 2 =9
Check: 7*9=63
There you go!
