QuestionDescribe and correct the error a student made in rewriting the equation to isolate yy. The student's work is displayed on the right. x=58+y1.981.98x=58+y1.98x2=58+y1.98x258=y\begin{array}{r} x=\frac{\sqrt{58+y}}{1.98} \\ 1.98 x=\sqrt{58+y} \\ 1.98 x^{2}=58+y \\ 1.98 x^{2}-58=y \end{array}
The error first appears in the line \square where the \square should be \square

Studdy Solution
The error first appears in the line 1.98x2=58+y1.98 x^{2}=58+y where the 1.98x21.98 x^{2} should be (1.98x)2(1.98x)^2 or 3.9204x23.9204x^2.
