start learning

Question		Answer
kwadrat sumy start learning		(a + b)² = a² + 2ab + b²
kwadrat różnicy start learning		(a - b) 2 = a2 - 2ab + b2
róznica kwadratów start learning		a2 - b2 = (a-b)(a+b)
pole trojkata start learning		(a x h)/2
pole trójkąta równobocznego start learning		a2 pierwiastek z 3 /4
pole kwadratu start learning		a2
przekatna kwadratu start learning		alfa = a pierwiastków z 2
pole prostokatu start learning		a x b
pole koła start learning		P = pi r2
