What are the zeros of the function f(x)=-x^2+13x-36

Galina-37 [17]

For this case we have the following function:

$f (x) = - x ^ 2 + 13x-36$

To find the zeros of the function we make $y = 0$ and solve for "x", then:

$0 = -x ^ 2 + 13x-36$

We multiply by -1 on both sides of the equation:

$0 = x ^ 2-13x + 36$

We factor the equation, for this we look for two numbers that, when multiplied, result in 36 and when added, result in -13. These numbers are -9 and -4.

$(-9) * (- 4) = 36\\-9-4 = -13$
