Q. and Robert are each trying to solve the equation \newlinex210x+26=0x^{2}-\sqrt{10x+26}=0 tions to \newlinex2=1x^{2}=-1 are \newlineii and \newlinei-i, but they are not sure how to use this
  1. Identify and Isolate Square Root Term: Identify the terms and isolate the square root term. x2=10x+26x^2 = \sqrt{10x + 26}
  2. Eliminate Square Root by Squaring: Square both sides to eliminate the square root.\newline(x2)2=(10x+26)2(x^2)^2 = (\sqrt{10x + 26})^2\newlinex4=10x+26x^4 = 10x + 26
  3. Rearrange Equation to Zero: Rearrange the equation to set it to zero. x410x26=0x^4 - 10x - 26 = 0
  4. Factorize or Solve Quartic Equation: Attempt to factorize or solve the quartic equation. This step involves complex algebraic techniques or numerical methods which might be beyond basic algebraic skills; hence, using a calculator or software might be necessary.
