x2 = 81 Square root both sides:- x = +/- 9
The two solutions are the conjugate complex numbers, +i*sqrt(11) and -i*sqrt(11), where i is the imaginary square root of -1.
x = 2 or -2

Use the quadratic equation formula to find the solutions to this equation.
13
They are x = -1 and x = 4.
x2+7x+3 = 0 Using the quadratic equation formula the solutions are:- x = -6.541381265 or x = -0.4586187349
There are no real solutions because the discriminant of the quadratic equation is less than zero.
There are no real solutions to this equation because you cannot take the square root of a negative number. However,x2 + 4 = 0x2 = -4sqrt(x2) = sqrt(-4)x = 2i, -2ihere are the imaginary solutions.
