Mav is older than Justin. Their ages are consecutive integers. Find Mav's age if the product of their ages is 42.

Let's assume that Mav's age is x years. Since their ages are consecutive integers, Justin's age is x + 1 years.

We are given that the product of their ages is 42, so we can write the equation:

x(x + 1) = 42

Expanding the equation, we get:

x^2 + x = 42

Rearranging the equation, we have:

x^2 + x - 42 = 0

Now, we can factorize the quadratic equation:

(x + 7)(x - 6) = 0

Setting the factors equal to zero, we find two possible solutions:

x + 7 = 0 or x - 6 = 0

Solving for x, we find:

x = -7 or x = 6

Since ages cannot be negative, we can conclude that Mav's age is 6 years.
