Question

What are the roots of f(x) = x2 – 48?

Answer 1

Answer:

x = 4 $\sqrt{3}$   and  x = -4 $\sqrt{3}$

Step-by-step explanation:

What are the roots of f(x) = x2 – 48 ?

this one can be solved directly    0 = xx - 48

xx = 48

x =  + root (48)    or   x = - root(48)

x = 4 $\sqrt{3}$   and  x = -4 $\sqrt{3}$
