three *x*sqrt((x + one)^ three)/(two *(x + one)) + sqrt((x + one)^ three) = zero
3 multiply by x multiply by square root of ((x plus 1) cubed ) divide by (2 multiply by (x plus 1)) plus square root of ((x plus 1) cubed ) equally 0
three multiply by x multiply by square root of ((x plus one) to the power of three) divide by (two multiply by (x plus one)) plus square root of ((x plus one) to the power of three) equally zero
