Square root 3a-2 = square root a/b (make b the subject)

b =

Step-by-step explanation:

Given

=

Clear the radicals by squaring both sides

( )² = ( )², that is

3a - 2 = ( multiply both sides by b )

b(3a - 2) = a ← divide both sides by (3a - 2)

b =

b = a/(3a-2)

Step-by-step explanation:

(3a-2)^½ = (a/b)½

Square both sides

3a - 2 = a/b

Reciprocate both sides

1/(3a-2) = b/a

b = a/(3a-2)

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
