How do you solve #5 =sqrt(1- 8x)#? Algebra Radicals and Geometry Connections Radical Equations 1 Answer louis b. · Stefan V. Mar 6, 2018 Answer: #x = -3# Explanation: You square both sides to get #25 = 1 - 8x# You subtract #1# from both sides to get #24 = -8x# Just divide both sides by #8# to get #x = -3# #5 = sqrt( 1 - 8x)# So #25 = 1 - 8x# #24 = - 8x# #3 = -x# #x = -3# Related questions How do you solve radical equations?
