Describe the set of points in space whose coordinates satisfy the given combination of equations and inequalities.
a. 1< _x^2 + y^2 + z^2< _4
b. x^2 + y^2 + z^< _4, x> _0

you probably already have the answer but anyways it's b. 15.0

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).
