Answer:
Let the function f(x) be (x-2)(x-5)
Now, this product on the right hand of the function is a zero product if the value of the function is 0.
⇒ (x - 2)(x - 5) = 0
Now, product of two factors is 0 only if any one of the factor is 0
So, we take each factor equal to 0
First take, x - 2 = 0
⇒ x = 2
Then, x - 5 = 0
⇒ x = 5
So, for these values of x i.e. x = 2 and x = 5 the product is the zero product.
