Question

f(x) = 2x² – 50

Find the zeros of the function
​

Answer 1

Answer x = 5 or -5

2x^2-50=0

2(x^2-25) = 0

2(x-5)(x+5)=0

(x-5)=0

Answer 2

Answer:

x = 5

x = -5

Step-by-step explanation:

       To solve for the zeros, we will solve for x when the function is equal to zero.

f(x) = 2x² – 50

0 = 2x² – 50

0 = 2(x - 5)(x + 5)

       We then have to parts to solve for this, as there are two zeros (since the x is being squared)

   x - 5 = 0  

      x = 5    

 -------------------

   x + 5 = 0

       x = -5
