9/29/08-An equation is true if each side of the equation simplifies to the same value or expression. Is the equation (a + b)² = a² + b² true? Explain. a=2 b=3 (2+3)²=6²=25 2²+3²=4+9=13 No, (a+b)² is not equal to a²+b² because 2+3=6 6²=25 and 2²+3²=4+9=13 so the equation is not true. You are adding and then squaring in the first one and in the second one you are squared each variable and then adding them together.
