Best answer
2log(base-a)x + log(base-a)2 = log(base-a)(5x+3)

Using logarthamic property alogb=log(b^a)

log(base-a)x^2 + log(base-a)2 = log(base-a)(5x+3)

Using addition property of logarthims loga+logb=logab

log(base-a)(2x^2)  = log(base-a)(5x+3)



Solving above equation we get



2x+1=0 or x-3=0

x=-1/2 or x=3
