\text{Hey there!}


\text{\underline{DIVIDE} both sides by the number 2 on your sides!}


\text{Like:}\bold{(2x^2)/(2)=(98)/(2)}


\bf{Cancel:(2)/(2)\ because\ it \ equals \ 1}


\text{Keep:}(98)/(2) \text{ because it helps us solve for our answer!}


\bf{(98)/(2)=49}


\text{Problem becomes:}\bf{\ x^2=49}


\text{Take the root of the newer equation:}\bf{\ x=\pm√(49)}


\text{Solve that}\uparrow \text{and we will get the value of x}


\boxed{\boxed{\boxed{\text{Answer: x = 7 or x = -7}}}}\checkmark


\text{Good luck on your assignment and enjoy your day!}
