step-by-step explanation:
rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another. their slopes then have to reflect perpendicular slopes. perpendicular slopes are opposite reciprocals of one another. for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2. so we look for that combination in our choices.
all of them satisfy that condition (so what's the question, i guess? )
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:
[tex]4x^2-0x-9[/tex]
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:
[tex]4x^2-0x-9[/tex]
[tex]=4x^2-6x+6x-9\\\\=2x(2x-3)+3(2x-3)\\\\=(2x+3)(2x-3)\\\\=(2x-3)(2x+3)[/tex]
therefore, the correct factorization of [tex]4x^2-0x-9[/tex] is (2x-3)(2x+3).
