Which are the roots of the quadratic function f(b) = 62 – 75? Select two options. b=573

Ob= -573

b=35

b= -35

Ob= 253

Step-by-step explanation:

Given

Required

Determine the roots

To get the root of the function, then f(b) must be 0;

i.e. f(b) = 0

So, the expression becomes

Add 75 to both sides

Take square roots of both sides

Reorder

Expand 75 as a product of 25 and 3

Split the expression

The options are not clear enough; however the roots of the equation are
