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
