Where is his mistake? give an explanation so i understand in the future. (1st correct answer gets brainliest)

Step 1 is correct, because you can multiply both sides of an equation by a same quantity.

Step 2 in incorrect: the left hand side is ok, but

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).
