A repairman charges an inspection fee plus $30 per hour. A customer with a coupon for 40% off the inspection fee pays $84 for a 2-hour repair. How many hours are worked when a customer pays $130 without a coupon?

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).

●yes, this statement is absolutely apt.

hope this you
