Final Answer
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: $(a-b)^2=a^2-2ab+b^2$

$x^2+x^2-2x+1-3=0$
Learn how to solve definition of derivative problems step by step online. Solve the quadratic equation x^2+(x-1)^2+-3=0. 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 1 and -3. Combining like terms x^2 and x^2. Use the complete the square method to factor the trinomial of the form ax^2+bx+c. Take common factor a (2) to all terms.
