It is a quadratic equation with one unknown variable, x which has no real roots.
Use the quadratic formula, with a = 1, b = -3, c = 2.
The equation 4x + 5 = 2 has the solution 4x = -3 and x = - 3/4 (minus 3/4).
The equation x2 - 5x - 24 = 0 has the two solutions 8 and -3 for x.
It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
x = 2.1374586088176875 x = -1.6374586088176875
{-1,7}
The equation does not have a real number solution. Using the quadratic formula will give it's conjugate pair complex solution.
There's an equals missing...
If the 64 has a minus sign, then the solution is x = +/-5 Simplifying gives 4x squared = 100 ie x squared = 25...
i think its 10
The value of x is 7
X=-3
(4.25, 0.25) is a solution.
It is a quadratic equation and its solutions are: x = -3/2 and x = 3
The equation has infinitely many solutions.
x equals negative b plus or minus the square root of b squared minus 4bc over 2a
