Teri wants to buy as many pencils and pens as possible. She wants three pencils for every pen. Each pencil costs $0.15 and
each pen costs $0.20. She cannot spend more than $6.50.
What is the maximum number of pens she can purchase?

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
