How do you solve #sqrt(6x^2 + 5x) = 2#? Algebra Radicals and Geometry Connections Radical Equations 1 Answer Lucy Jul 29, 2018 #x=1/2# or #x=-4/3# Explanation: #sqrt(6x^2+5x)=2# Square both sides #6x^2+5x=4# #6x^2+5x-4=0# Using the quadratic formula, #x=(-5+-sqrt(25+96))/12# #x=(-5+-sqrt121)/12# #x=(-5+-11)/12# #x=(-5+11)/12# or #x=(-5-11)/12# #x=1/2# or #x=-4/3# #6x^2+5x-4=(x-1/2)(x+4/3)=(2x-1)(3x+4)# Answer link Related questions How do you solve radical equations?
