$\left(d+3e\right)\left(d+3\cdot -e\right)$
Learn how to solve simplification of algebraic expressions problems step by step online. Simplify the expression (d+3*e)(d+3*-e). Multiply 3 times e. Multiply 3 times -e. The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: (a+b)(a-b)=a^2-b^2..
