$\left(3-x\right)^2+\left(-x+3\right)\left(7x+4\right)-18+2x^2$
Learn how to solve simplification of algebraic expressions problems step by step online. Simplify the expression (3-x)^2-(x-3)(7x+4)+-182x^2. Simplify the product -(x-3). A binomial squared (difference) is equal to the square of the first term, minus 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. Subtract the values 9 and -18. Combining like terms x^2 and 2x^2.
