@fivestudy_official: SAT Math algebra: (x + y)². Is it x² + y²? It's one of the most common mistakes on the test. Draw the square and you find x², y², and two xy rectangles, so (x + y)² = x² + 2xy + y². Check with numbers: (3 + 4)² = 49, but 9 + 16 is only 25. Keep the middle term. fivestudy.com #SATMath #DigitalSAT #SATPrep #Algebra #StudyTok
