$\left(3x\right)^2-42x+49-5\left(2x+1\right)\left(x-2\right)=-x+3x+1$
Learn how to solve problems step by step online. Solve the equation (3x-7)^2-5(2x+1)(x-2)=-x+3x+1. 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. The power of a product is equal to the product of it's factors raised to the same power. Move everything to the left hand side of the equation. Combining like terms -42x and x.
