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
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).
The most surefire way to find the zeroes of a quadratic are to apply the quadratic formula. The formula says that the zeroes of quadratic equations which are generally written as ax2+bx+c=y can be found by taking (-b+/-(b2-4ac).5)/2a or if this notation makes no sense... negative b plus or minus the square-root of b squared minus four ac all over two a. Note: if b squared minus four ac is less than zero, the function has non-real roots
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
It is a quadratic equation in X, with two real roots.
3x2 + 2x - 8 = 0 is a quadratic equation.
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 is a quadratic equation and its solutions are: x = 4 or x = -9
It can be solved by using the quadratic equation formula.
With the help of the quadratic equation formula
It is a quadratic equation with one unknown variable, x which has no real roots.
