Answer this question as soon as possible (discrete math question)
1. is ⊆ ⊆ is either a proper subset of the other?
(a) = { ∈ ℝ| cos ∈ ℤ}, = { ∈ ℝ| sin ∈ ℤ}

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

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).

step-by-step explanation:

i think its about 8
