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

x = 5

x = -5

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
