3 (a+7) = −33 Step By Step Equation

a=-18

Step-by-step explanation:

3 (a+7) = −33

3a+21=-33

3a=-54

-54/3=-18

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).
