That is a quadratic equation and must be factorised using two brackets. It is just a little confusing to recognise it as a quadratic as the middle x value is not there so we treat it as 0 - which means the two numbers must cancel each other out: (2x + 1) (2x - 1)
x = plus or minus 6.
Solve this problem -x squared -40x- 80 =0
The expression x squared minus x can be simplified by combining like terms. This results in x^2 - x = x(x - 1), where x^2 represents x squared and x represents x to the first power. This expression represents a quadratic equation in factored form, where x and x-1 are the factors.
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2).
It is a quadratic equation and its solutions are: x = -3/2 and x = 3
The solutions to the quadratic equation are: x = -1 and x = 6
3x2 + 2x - 8 = 0 is a quadratic equation.
It is a quadratic equation in X, with two real roots.
x equals negative b plus or minus the square root of b squared minus 4bc over 2a
Use the quadratic formula, with a = 1, b = -3, c = 2.
It can be solved by using the quadratic equation formula.
