Solution equation: √ 18a - √ 1 / 8A + 4 √ 0.5A Calculation questions

Solution equation: √ 18a - √ 1 / 8A + 4 √ 0.5A Calculation questions

It's not an equation. It's simplification
The original formula = 3 √ 2A - [(√ 2) / 4] a + (2 √ 2) a
=[(13/4)√2]a

It is known that x + 2 / A + X_ B of 3 = (x + 2) (x)_ 3) Find the value of a and B

The value of a and B is known as (x-1) (x + 2) (2x-3) = (x-1) (a) + (9x + 2) (b). Find the value of a and B. answer the first question first: the following formula is divided first, then the denominator becomes (x-1) (x + 2), and the molecule becomes a

Given that 5x-4 / (x + 1) (2x-1) = A / x-1-b / 2x-1, try to find the value of a and B

5x-4 / (x + 1) (2x-1) = A / x-1-b / 2x-1
5x-4/(x+1)(2x-1)=[A（2x-1）-B（x-1）]/(x+10（2x—1）
5x-4=A（2x-1）-B（x-1）
5x-4=(2A-B)x-A+B
2A-B=5 -A+B=-4
The solution is: a = 1, B = - 3
