\huge\text{Hey there!}


\mathsf{25x^2=49}


\textsf{DIVIDE by 25 to BOTH SIDES}


\mathsf{(25x^2)/(25)=(49)/(25)}


\textsf{Cancel out: }\mathsf{(25)/(25)}\textsf{ because it gives you 1}


\textsf{Keep: }\mathsf{(49)/(25)}\textsf{ because it helps us solve for x}


\textsf{New equation: }\mathsf{x^2 = (49)/(25)}


\textsf{TAKE the SQUARE ROOT}


\mathsf{x\pm \sqrt{(49)/(25)}}


\mathsf{\sqrt{(49)/(25)}= 1.4}


\mathsf{- \sqrt{(49)/(25)}= -1.4}


\boxed{\boxed{\large\text{Answer: \huge \bf x = 1.4 or x = -1.4}}}\huge\checkmark
