Ireplaced a square window with a retangular one the new window is 3ft wider and 2ft higher than the square one it has an area of 42ft how long was the side of the original square window

-81 -56 -27 0 81

step-by-step explanation:

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).
