The answer should be x=15 because once u subtract 15-15 u get 0 and then u substitute 15 in "x" and then. Multiply 0 by everything else n u get 0:))

we have the function

\(f(x)=(x-15)(x+1)(x-10)\)

we know that

The zero's of the function are the values of variable x when the value of the function is equal to zero

so

in the given function the zero's are

\(x=15\\x=-1\\x=10\)

therefore

the answer is

\(x=15\)
