Step-by-step explanation:
(1)
given
4x² = 81 ( divide both sides by 4 )
x² = ( take the square root of both sides )
x = ± = ±
---------------------------------------------------------------------
(2)
subtract 7 from both sides
(4x - 3)² = 32 ( take the square root of both sides )
4x - 3 = ± = ± 4
Add 3 to both sides
4x = 3 ± 4 ( divide both sides by 4 )
x = ±
