Respuesta :

zeros is a value of x when y, or f(x)=0
2x²-50=0
2(x²-25)=0
2(x-5)(x+5)=0
x-5=0
x+5=0
x1=5, x2=-5
zeros are 5 and -5
When f(x) = 0, 

[tex]2x^2 - 50 = 0[/tex]

[tex]2(x^2 - 25) = 0[/tex]

[tex]2(x- 5)(x + 5) = 0[/tex]

[tex](x - 5) = 0 \ or \ (x + 5) = 0[/tex]

[tex]x = 5 \ or \ x = -5[/tex]

Answer : x = 5 or -5
