Questions & Answers
Q: How do you solve linear equations?
To solve linear equations, isolate the variable by moving constants to the other side of the equation. For example, in the equation x + 1 = 0, subtract 1 from both sides to get x = 1.
Q: How do you solve quadratic equations by completing the square?
To solve quadratic equations by completing the square, move the constant term to the other side of the equation. Find the "magic number" (half the coefficient of x squared) and add it to both sides. Take the square root of both sides and solve for x.
Q: Can cubic equations be solved by factoring?
Yes, cubic equations can be solved by factoring. Group the terms and factor out the common factor. Set each factor equal to zero and solve for x.
Q: How can quartic equations be solved without using the quartic formula?
Quartic equations can be solved by dividing by x^2 and factoring. Divide each term individually and factor out the common factor. Solve the resulting quadratic equation to find the possible values of x.
