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.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
