Provide an appropriate response.Tina was asked to solve the following problem: "The product of two consecutive numbers is 90. Find the numbers." Tina's solution is given below. Do you agree with her conclusion? If not, why not? x(x + 1) = 90x2 + x = 90x2 + x - 90 = 0(x + 10)(x - 9) = 0x = -10 or x = 9The pair of numbers is 9 and 10
What will be an ideal response?
There is nothing in the problem to suggest that the two numbers must be positive thus there is no reason to discard the negative solution. There are two solutions: the pair of numbers is 9 and 10 or -10 and -9.
