Learn how to solve classify algebraic expressions problems step by step online. Find the break even points of the expression d=(x+3)^2-x^2. A binomial squared (sum) is equal to the square of the first term, plus the double product of the first by the second, plus the square of the second term. In other words: (a+b)^2=a^2+2ab+b^2. Cancel like terms x^2 and -x^2. Rearrange the equation. Factor the polynomial 6x+9 by it's greatest common factor (GCF): 3.
