Question

kindly give me the solution of this question step by step in written form urgent

Answer 1

log x+2(x^3-3x^2-6x+8)=3
or, (x+2)^3=x^3-3x^2-6x+8
or, x^3+3×x^2×2+3×x×4+8=x^3-3x^2-6x+8
or, 6x^2+12x+3x^2+6x=0
or, 9x^2+18x=0
or, 9x(x+2)=0
so 9x=0
or x=0
so x not equals to 0
then,
or,, x+2=0
x= -2 (B)
hope this helps
