Factor the expression. k2 + 5kf – 50f2 a)(k + 10f)(k + 5f) b)(k – 10f)(k + 5f) c)(k + 10f)(k – 5f) d)(k – 10f)(k – 5f)

 The correct option is

(C)

Step-by-step explanation:  We are given to factor the following quadratic expression :

To factor the given expression, we must find two integers with sum 5 and product -50.

The factorization of given expression (i) is as follows :

Thus, the required factored form of the given expression is

Option (C) is CORRECT.

3x + 4y -25 =0 represents the amount of change sianna should recieve

f(x)=2/3x-8, which give g(x) the greatest value.
