Two numbers that when added equal 56 and when multiplied equal 783?
X + Y = 56 [therefore] X = 56 - Y XY = 783 [therefore] (56 - Y)(Y) = 783 56Y - Y^2 = 783 solve for Y, then don't forget to plug Y back into the original and find "X" (X = 56 - Y ) a+b = 56 AND: ab = 783 substitution: a = 56-b (from addition equation) put this back into the multiplication equation: (56-b)b = 783 expansion: 56b -b^2 = 783 rearrange: -b^2 + 56b - 783 quadratic formula: b = (-56+sqrt(3136-4(-1)(-783))) / -2 and b = (-56-sqrt(3136-4(-1)(-783))) / -2 b=27 and b=29 from the addition equation: 56-27 = a=29 56-29 = a =27 it's kind of a "repeat" question
The product of two consecutive odd integers is 783?
Oh, isn't that just a happy little math problem? Let's think about it together. If we have two consecutive odd integers, we can call them n and n+2. When we multiply them together, we get n(n+2) = 783. By solving this equation gently, we find that the two numbers are 27 and 29.
