\textsf{Hey there!}


\textsf{Switch the equation: }
\mathsf{-2y^2+ 50}


\mathsf{-2y^2+2*5^2}


\mathsf{2(- (2y^2)/(2)+ (2*5^2)/(2))}


\mathsf{2(- y^2)+5^2)}


\mathsf{5^2= 5*5 = 25}


\mathsf{2(-y^2+25)}\\\mathsf{2(-y^2+5^2)}\\\mathsf{Flip: 2(5^2-y^2)}\\\mathsf{2((5-y))((y+5))}\\\boxed{\boxed{\mathsf{Thus, your\ answer\ is: \boxed{\bf{2(-y+5)(y+5)}}}}}\checkmark
