2x2 - 6x - 25 = 0. Solutions are 5.34 and -2.34
It is a quadratic equation that has 2 solutions
Using the quadratic equation formula: x = 1 or x = -10
x2 - 21x = 72x2 - 21x - 72 = 0(x - 24) (x + 3) = 0x = 24x = -3
There are no real solutions. The discriminant (b squared -4ac) is less than 0, so there are 2 imaginary solutions and 0 real ones.
2x2 - 3 = 13 So 2x2 = 16 x2 = 8 So that x = ±2√2
2x2 - 6x - 25 = 0. Solutions are 5.34 and -2.34
It is a quadratic equation that has 2 solutions
2(x - 2)(x + 4) = 0 x = 2, -4
Using the quadratic equation formula the solutions are:- x = -27.0382854 and x = 90.5382854
Using the quadratic equation formula: x = 1 or x = -10
24x. For example, if x is 2, then 24x equals 48.
x2 - 21x = 72x2 - 21x - 72 = 0(x - 24) (x + 3) = 0x = 24x = -3
It has two equal solutions for x which are x = 2 and x = 2
2x2 equals 5
There are no real solutions. The discriminant (b squared -4ac) is less than 0, so there are 2 imaginary solutions and 0 real ones.
3(2) + 24x + 48 = 0 6 + 24x + 48 = 0 24x + 54 = 0 24x + 54 - 54 = 0 - 54 24x = -54 24x/24 = -54/24 x = -9/4 x = -2 1/4
