Which are the roots of the quadratic function f(b) = b2 – 75? Check all that apply.Which are the roots of the quadratic function f(b) = b2 – 75?

For this case, what we must do is equal the function to zero:
 b ^ 2 - 75 = 0
 From here, we clear the value of b. We have then:
 b = + / - root (75)
 We rewrite:
 b = + / - root (3 * 25)
 b = + / - 5 * root (3)
 So, the roots are:
 b1 = 5 * root (3)
 b2 = -5 * root (3)
 Answer:
 The roots of the quadratic function are: 
 b1 = 5 * root (3)
 b2 = -5 * root (3)
