Final answer to the problem
Step-by-step Solution
Specify the solving method
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: $(a-b)^2=a^2-2ab+b^2$

$\left(x+3\right)\left(x-1\right)=5+x^2-4x+4$
Learn how to solve equations problems step by step online. Find the roots of (x+3)(x-1)=5+(x-2)^2. 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. Add the values 5 and 4. Move everything to the left hand side of the equation. Multiply the single term x-1 by each term of the polynomial \left(x+3\right).
