Simplifying
(2a + 5)(3a + -4) = 0

Reorder the terms:
(5 + 2a)(3a + -4) = 0

Reorder the terms:
(5 + 2a)(-4 + 3a) = 0

Multiply (5 + 2a) * (-4 + 3a)
(5(-4 + 3a) + 2a * (-4 + 3a)) = 0
((-4 * 5 + 3a * 5) + 2a * (-4 + 3a)) = 0
((-20 + 15a) + 2a * (-4 + 3a)) = 0
(-20 + 15a + (-4 * 2a + 3a * 2a)) = 0
(-20 + 15a + (-8a + 6a2)) = 0

Combine like terms: 15a + -8a = 7a
(-20 + 7a + 6a2) = 0

Solving
-20 + 7a + 6a2 = 0

Solving for variable 'a'.

Factor a trinomial.
(-5 + -2a)(4 + -3a) = 0

Subproblem 1
Set the factor '(-5 + -2a)' equal to zero and attempt to solve:

Simplifying
-5 + -2a = 0

Solving
-5 + -2a = 0

Move all terms containing a to the left, all other terms to the right.

Add '5' to each side of the equation.
-5 + 5 + -2a = 0 + 5

Combine like terms: -5 + 5 = 0
0 + -2a = 0 + 5
-2a = 0 + 5

Combine like terms: 0 + 5 = 5
-2a = 5

Divide each side by '-2'.
a = -2.5

Simplifying
a = -2.5
Subproblem 2
Set the factor '(4 + -3a)' equal to zero and attempt to solve:

Simplifying
4 + -3a = 0

Solving
4 + -3a = 0

Move all terms containing a to the left, all other terms to the right.

Add '-4' to each side of the equation.
4 + -4 + -3a = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -3a = 0 + -4
-3a = 0 + -4

Combine like terms: 0 + -4 = -4
-3a = -4

Divide each side by '-3'.
a = 1.333333333

Simplifying
a = 1.333333333
Solution
a = {-2.5, 1.333333333}

Hitman42 [59]

A specialized accounting book for accumulating and posting business transactions into specific categories is a ledger.

<h3>What is a ledger?</h3>

A ledger is a specialized accounting tool.  It can also be described as a financial book or computer program.

In the ledger, information from accounting journals is accumulated and posted into specific categories matching the type of accounts.

From the ledger, the trial balance is extracted, which forms the basis for preparing the financial statements that show an entity's financial profitability and position.

Thus, a specialized accounting book for accumulating and posting business transactions into specific categories is a ledger.
