Question 589082
We know that x and y are consecutive numbers. Suppose y is greater than x then y = x +1
Their product is 90. so x(x + 1) = 90
OR x^2 + x = 90
x^2 + x - 90 = 0
Solve the quadratic equation, you will find two values of x. From those two values of x, find two values of y by using equation y = x + 1.

Hope it helps:)
