Answer:
The zeros of the equation are x=10 and x=-10
Step-by-step explanation:
we know that
The zeros of the quadratic equation are the values of x when the value of the function is equal to zero
we have
[tex]f(x)=3x^{2} -300[/tex]
so
For f(x)=0
[tex]3x^{2} -300=0[/tex]
[tex]3x^{2}=300[/tex]
[tex]x^{2}=100[/tex]
square root both sides
[tex]x=(+/-)10[/tex]
therefore
The zeros of the equation are x=10 and x=-10
