Solve x^2+4x
Solve ax² + bx + c = 0 using the quadratic formula with discriminant analysis.
x2+4x
Solve by factoring the quadratic and applying the zero product property:
Factor out x:
x(x + 4) = 0
If a product equals zero, at least one of the factors must be zero. Set each factor equal to zero and solve:
x = 0
x + 4 = 0 → x = −4
x = -4, 0
How to solve x^2+4x
To solve x^2+4x, we can try factoring, use the quadratic formula, or complete the square. The solution is x = -4, 0.
This is a second-degree quadratic equation — the highest power of the variable is 2. Quadratic equations can have two real roots, one repeated root, or two complex roots.
Frequently asked questions
What is the answer to x^2+4x?
The answer is x = -4, 0.
What method is used?
factoring when possible, or the quadratic formula x = (−b ± √(b²−4ac)) / 2a. The discriminant b²−4ac determines the number and type of solutions.
How do I verify this?
Substituting the solution(s) back into x^2+4x confirms both sides are equal.
